What Is the Difference Between Mechanical, Civil and Electrical Engineering?

When we talk about engineering, it's easy to forget that the profession is made up of very separate disciplines. The three main engineering branches are Civil Engineering, Electrical Engineering and Mechanical Engineering, and there are significant differences between them.

Civil engineers are concerned with the design, construction and maintenance of the built environment we see around us every day. They're responsible for not only ensuring buildings are constructed safely and in the right way, but also creating the necessary infrastructure of bridges, roads, dams and railways. Civil engineering is traditionally subdivided into a number of further disciplines, which include environmental, geotechnical, construction, coastal, transportation, water resources, structural, material engineering and surveying.

Civil engineers work in both the public and private sectors. This means they could be undertaking infrastructure schemes for local government as well major projects for multinational companies, but also much smaller jobs for private individuals. Major projects which civil engineers have been heavily involved in recently include the 2012 Olympic stadium and Crossrail, which is extending the rail network beneath London.

The job of electrical engineers on the other hand, is to study electricity, electronics and electromagnetism and how they can best be applied. This means they design, maintain and improve products that are powered by or produce electricity. So electrical engineers are involved with the development and construction of large-scale electrical systems for power transmission and distribution, and control motors. Sometimes electrical engineers are also called electronics engineers, though electronics engineers are more specifically focused on using electricity to power electronics. This means that an electronics engineer might design the computer system for a car, while an electrical engineer would deal with the electrical systems that powered those electronics.

Of particular interest to electrical engineers currently is finding new ways to create and then use renewable power more efficiently in our daily lives. Consequently, they are increasingly involved in the development of solar, wave and wind systems and in the development of electric cars and their charging points.

Finally, mechanical engineers handle the design and construction of machines. This can see them working on all manner of engines and turbines for all kinds of applications - cars, lorries, ships, aircraft, pumps and fans, air-conditioning and refrigeration systems, building services, industrial plants and manufacturing processes.

So they need to know about many different specialist areas such as thermodynamics, fluid mechanics and mechanical design, as well as computer and electronics engineering, acoustics, noise and vibration control and increasingly medical bio-technology.

In this field, they use their expertise as the 'motion specialists' in a team that's working to design, build and install artificial body parts. So they will work with doctors and biologists to create such things as artificial limbs that have to be designed to withstand the stresses of everyday life, using materials that are compatible with the human body.

Each of these three areas of engineering offers exciting opportunities for those in the profession. With new technologies, materials and ideas being developed all the time, this will lead to ever greater specialisation, with each branch becoming even more sub-divided and varied.

Four Benefits of Hiring Professionals for Your Garage Door Repair Needs

Many do-it-yourselfers are capable of simple garage door servicing. However, not all are comfortable with more complicated jobs like fixing the opener and replacing the tracks. These usually require the assistance of a garage door repair professional.

A seasoned garage door repair professional has the requisite knowledge and training to get the job done quickly and accurately. He or she will also have the appropriate tools and safety equipment to efficiently conduct all tasks related to the repair. Garage door maintenance companies may also be able to provide you with certain benefits such as warranties. These are some benefits you'll get when working with a professional.

1. Knowledge

Professionals are trained to understand in-depth how each type of garage door works. They also know exactly how to troubleshoot various problems that may be wrong with a particular style or brand of door, and they are able to quickly assess which parts may need to be replaced.

2. Tools

Garage door repair requires specialized tools that may be too expensive for you to purchase for a one time job. These tools may be the only appropriate ones for a specific job, such as cutting heavy duty springs. Attempting to use inferior tools that are not built for this type of labor can compromise any repair and put you in possible danger.

3. Safety

Knowledgeable garage door repair companies are aware of all the risks that a layperson may not know. Doors in the process of being fixed have been known to drop on people at random because of a bad spring or track. These doors can weigh up to 500 pounds, and these accidents have proven fatal in the past. This is why season repairedmen work in pairs or teams to prevent such tragic occurrences. They know where to hold the door while it is being serviced.

4. Guarantee

Repairs handled by professional companies are typically guaranteed with a warranty for all labor and parts. This is not something that you can have if you conduct all of your own servicing. However, by hiring specialists, you are protected against the possibility of any problems in the future in which repair may be needed again.

With all these reasons to ponder, why would you rather attempt this difficult and time-consuming job all by yourself? Why not spend a little money and have a consensus pro do what he or she does best? You are not only freeing up your time, but also investing in the safety and functionality of your home.

Numerology Magic Square Talismans as Money Charms

Magic Squares make a potent talisman or charm for enhancing certain talents and abilities of their bearer. Numerology provides us with a powerful way to construct a personal money charm just for you. Let's see how this can be done.

Date of Birth as a Sigil

In numerology and astrology, your Date of birth is a defining signature element for you. Your entire reading in both disciplines is built around this number. So, if I wish to construct a magic talisman using numbers and associate it's power with you, using your date of birth in the charm is a natural way to build this association.

There are other means, such as using your name or signature in the talisman, but since I'm using numbers to construct the charm anyway, your date of birth makes a perfect sigil to represent you.

Yantra Magic Squares

Yantra magic squares are magic squares built using your date of birth, and your Life Path number as the top row of the square. They are powerful good luck charms for the person they are constructed for. But, they don't necessarily attract wealth and riches to the person.

Eight - The Money Number

In numerology as well as other physic disciplines, eight is associated with money and riches. To specifically attract more money to a person, I can construct a magic square talisman where the rows and columns sum to a number which reduces to (8) using fadic addition. The numbers: 26, 35, 44, 53, 62, 71, 80, 98, and 107 all have this properity.

So, in order to create my talisman, I start with someone's Yantra magic square, and then change the last box in the top row from their Life Path number, to a number which produces a square where the rows sum to (8).

Let's look at an example to see my meaning.

Johnny Depp's Money Talisman

Actor Johnny Depp was born on June 9th, 1963; so his Life Path number would be (7) as shown below.

Life Path = (06 + 09 + 1963) = (1978) = (1 + 9 + 7 + 8) = (25) = (7)

The first row of his Yantra Magic square we be his Month, Day, Year (less century) and his Life Path number, and would look like this:

( 6 )( 9 )( 63 )( 7 )

The row totals (85) which reduces to (4) by fadic addition. If I substitute a (2) in the last box on the row for his Life Path number of (7), then the resulting row will sum to (80) which will reduce to and (8) using fadic addition.

Making the substitution, and then calculating the rest of the Magic square by formula, I get the following:

( 6 )( 9 )( 63 )( 2 )

( 61 )( 4 )( 4 )( 11 )

( 3 )( 64 )( 8 )( 5 )

( 10 )( 3 )( 5 )( 62 )

Summary

So with a little work, I can create a (4 x 4) Yantra magic square focused on a particular person, and targeted to draw money and financial success to them.

6 Common Garage Door Repair Problems

Garage door repair is something all homeowners have to deal with at some point in time. Understanding the common problems you may face can make it easier to explain the issue to the technician when he or she arrives. It can also help you understand what the service technician is doing to fix the problem.

1. You Push the Button, but It Does not Close

Modern garage door openers have built-in sensors that feel the resistance on the hatch. If there is a broken spring or hinge, then mechanics will not try to pull the chain. In some instances, the opener is the problem. Only a qualified technician can diagnose the issue.

2. You Can Hear the Opener Running, but Nothing Happens

Openers wear out over time, and the gears are usually the first thing to go. If these gears are stripped, they cannot move the chain, which raises and lowers the hatch. In some cases, you can replace the gears. In others, you have no choice but to replace the entire system.

3. You Have a Kick Out Door and Want It Repaired

You may find some technicians who are willing to fix your one-piece door, better known as a kick out. However, as these are outdated systems, they are unsafe. While yours may seem to be in decent working condition, you should have it replaced with a newer, safer model.

4. The Hatch Opens Stiffly and Makes Noise

Noisy garage doors are a common problem. Your garage door repair technician will first replace the rollers in order to solve the problem. Most companies use plastic rollers that wear out. When having them replaced, you should ask for low-resistance rollers. This model works smoother and is lower maintenance than traditional options. They are worth the additional cost.

5. You Have an Old Opener and Want It Replaced

If your opener is not working properly, you may wonder if it has to be replaced. Your garage door repair technician will be able to look at your equipment and make a determination about whether they have the parts needed to fix the problem without replacing the entire unit. However, in the interest of safety, if your old system does not have a safety beam, you need to exchange it for a newer system.

6. The Rollers Are Out of the Track and It's Pulling the Door

This is actually a very common garage door repair issue. There are several different reasons why this could happen. Your rollers could be so worn out that they work their way out of the track. Sometimes the track itself has been bent or is obstructed by something within the room. Other times, the large springs at the top are broken and cause the panels to pull off track.

One of the most overlooked causes is when you've accidentally hit a panel with your vehicle. The damage may look insignificant. However, if left unrepaired, over time it will pull the panel off track. Thankfully, the solution is relatively easy to fix, and it can be repaired.

Garage Door Repair - 5 Simple Things to Check

Garage door repair may often be done by the homeowner themselves. There are at least 5 simple things to check, before calling a professional. Some repairs are extremely easy. For example, a stiff or a squeaky door will merely require a good cleaning and lubrication. Other repairs, such as repairing a torsion spring, are extremely dangerous and require help from a professional.

Before proceeding to the repair, make sure to unplug your garage door opener, so that you do not get an electric shock while you are repairing your garage door. You will most likely be standing on a ladder, which is a very bad place to get an electric shock, since you may also fall off the ladder. Also, remember to wear safety glasses when working with power tools.

Here is a list of things to check before calling for a professional for your garage door repair:

1. Check the Metal Tracks for Damages

This easy garage door repair tip may often solve the problem very fast. The metal tracks often may have dents or bumps. If you find any such damages, strike the damaged part of the track with a wood block and a hammer to straighten the track.

2. Check the Alignment of the Tracks

If the tracks are not aligned well, they may be causing the door not to work. It's not always necessary to unscrew the tracks; you can just try to loosen the bolts or screws and to tap the tracks slightly into position. Use a level to check the alignment of the tracks. Aligned tracks will let you be done with your garage door repair in no time.

3. Clean and Dry the Tracks

Even though it may sound obvious, but hardened dirt and old lubricant may be the cause of the garage door sticking. In this case, your garage door repair may consist of merely cleaning the tracks and then drying them. You can use regular cleaners to clean the tracks.

4. Lubricate the Tracks and the Rollers

Merely lubricating both, the tracks and the rollers, can fix the problem and conclude your garage door repair in no time. For lubrication, you may use a lubricant spray or a silicon spray. It is probably better to lubricate the tracks after cleaning them. Actually, any movable part will benefit from lubrication.

5. Tightening the Loose Bolts and Screws

Bolts and screws tend to become loose with time. Try to check all of the screws and bolts involved in the opening/closing mechanism of your door. Sometimes, merely tightening them may solve the whole problem. If you cannot tighten the screws, because the holes themselves have become loose, then you can use a "wood filler" or pieces of normal wood to fill the holes.

What Not to Do?

If you have tried every one of the above solutions, and none of them have worked, the problem may be the door spring. However, it is advised not to perform your garage door repair if the problem seems to be the spring, especially if it's a torsion spring. Unfortunately, there have been numerous cases, where people have gotten injured or even killed by the garage door springs. One of the most common injuries is a hit in the head, resulting in serious trauma to the brain.

If you have doubts your garage repair, by no means should you attempt it. It generally will not cost too much. However, a professional will save you from any injuries.
