HOW do I SELECT A STEP DOWN TRANSFORMER?
By looking to the number of turns in the Primary and Secondary Coils. "A Step down transformers are designed to reduce electrical voltage. Their primary voltage is greater than their secondary voltage. This kind of transformer "steps down" the voltage applied to it."
What will break down and remove contact cement?
This depends on which kind you're using. The manufacturer usually produces a solvent. go on line or call them.
How many methods can enable construction of pile foundations and how?
You can use hammer, press or vibrationdrivers. The most common are hammer and vibrationdrivers, which pound on or vibrate the pile to sink it into the ground. Where noise or vibration would be a no-no, pressdrivers can be employed.Hammer drivers can be operated mechanically, hydraulically or pneumatically. In all types of hammer driver, the ram is raised in a slide and allowed to drop on the head of the pile. Repeat until the pile is at the required depth. Make sure you are wearing your ear protectors if you're nearby. Hammer driving can also have a detrimental effect on nearby buildings, as the seismic waves generated are powerful. Typically the ground around the driver will jump a few inches with each blow.(There is a method in which the ram is constructed to form a single cylinder diesel engine but I'm unfamiliar with this technique. Most of the pile drivers I've seen were hydraulically raised hammer or mechanical vibration types.)Vibration drivers operate on a different principle. Usually there is a hydraulic arm and a motor driving an eccentric cam or a shaft which is weighted to put it out of balance; the vibration causes the earth to assume liquid-like properties and the pile slowly glides in under the pressure of the pile driver arm. This is nowhere near as noisy as hammer driving. Unfortunately the powerful seismic vibration can have a bad effect on nearby buildings and can be quite unpleasant for nearby humans.Press drivers use (usually) hydraulic brute force to push the pile in; doing it like this requires Big Science but has the advantage of being relatively quiet and kind to nearby foundations and people.For driving smaller pilings or for shoring trenches, the bucket of a digger can be used to good effect. Just raise it up and bring it down hard.
What does specified mean?
To break something down with specific details.Like if you want ice cream you have to specify what kind of ice cream you would like.
What do substations reduce the voltage for?
A: Substations step down the transmission voltage for distribution for the local area. The reason being that their input is in the range 0f 475 Kv trying to distribute that kind of hi voltage would be totally impractical because of insulation. So a substation step down the hi voltage to a distribution level of 16kv or so.

Is a basketball shape a sphere?
technically, no because it has thousands of ridges on it for friction, along with the black part that kind of dips down. if you are looking for a nonspecific answer that is simple, then yes, it is.
