Getting on and off an escalator is simple for most people. However, some people are scared of riding an escalator because of a previous bad experience, stories they may have heard, warning signs or just because escalators are big and make a lot of noise. This article will teach you how to correctly get on and off an escalator safely. Edit Steps 1 Identify the escalator you are planning to embark on. Use building maps and floor plans to make sure it is the correct one. If these are unavailable, you will have to guess, but make sure you have a plan to get back should you have gotten on the wrong one. 2 Walk up to the escalator and think about what you are going to do. It is important to time things just right, or you may fall and injure yourself. Face the moving steps and concentrate. It is advised to ask a few friends to hold up the people behind you if you plan to take anymore than a few seconds doing this. This way it is less likely someone will bu...

If you are afraid of escalators, here is how to overcome that fear. Edit Steps 1 Observe how other people are using the escalator. 2 Approach it deliberately, slowly. Step out of the way to back off and wait a while--if you wish to work up to it a little. 3 Notice that most people seem to love and enjoy escalators, and approach them happily even with joy. 4 Think about why other users do not seem to be afraid. Why are you afraid? Do you just need to go for it, a few times? 5 Take your time getting on and off the escalator to be safe, and not to fall. Don't rush: keep control of your emotions, and follow steps below. 6 Grasp the moving handrail and step on. Be still. Hold onto the handrails. 7 Use the escalator carefully. If you have average eyesight, coordination, balance and agility it is considered safe to use an escalator. Is their danger--well, probably no more than falling on ordinary steps or stairs. That on...

Escalators work in much the same way that conveyor belts do, and in most cases the moving stairs are actually on a belt that rotates around a set of gears at a certain fixed speed. The gears tend to be large, and typically sit just below the steps. They are electrically powered and, as they turn, the steps move. In most cases the stairs themselves are just grooved metal that lies flat as it travels down the backside, beneath the floor, and back around again. In most cases this same system controls handrail motion, though this is an additional moving part. These machines often look really imposing, but from a mechanical perspective they tend to be pretty straightforward. Repairs are also usually pretty easy, though they can take a lot of time since they involve, in most cases, major moving parts. Accessibility is often the hardest part about servicing gears and other internal parts.  he core machinery for these large appliances is usually hidden beneath the steps...

Rainbow Formation Dispersion of Light by Prisms Rainbow Formation Mirages One of nature's most splendid masterpieces is the rainbow. A rainbow is an excellent demonstration of the dispersion of light and one more piece of evidence that visible light is composed of a spectrum of wavelengths , each associated with a distinct color. To view a rainbow, your back must be to the sun as you look at an approximately 40 degree angle above the ground into a region of the atmosphere with suspended droplets of water or even a light mist. Each individual droplet of water acts as a tiny prism that both disperses the light and reflects it back to your eye. As you sight into the sky, wavelengths of light associated with a specific color arrive at your eye from the collection of droplets. The net effect of the vast array of droplets is that a circular arc of ROYGBIV is seen across the sky. But just exactly how do the droplets of water disperse and reflect the light? And wh...
