Load * Distance ., will act on the CG

Speed regulation is the percentage of speed change, generally this is only calculated on devices which are attempting to maintain a constant speed. For example, on some industry motors, they need to maintain a constant RPM. When the motor has weight bearing on it, it is called a load, and the speed may change slightly. Formula: high speed (or no load) = nL Lowest speed (or full load) = fL (nL - fL) / fL x 100 = % regulation. example: 1700 rpm no load, 1500 rpm full load. (1700 - 1500) / 1500 x 100 = 200 / 1500 x 100 = 0.1333 x 100 = roughly 13% speed regulation.

It depends upon whether or not the wall is load bearing. If load bearing, the distance between standard studs is nominally 16 inches. If not load bearing, it can be 24 inches. There may be complications at the ends of the wall and doors and windows will also increase the number of 2x4's that are needed. A good rule of thumb is to figure one per foot. So in your case that would be 16.

Mechanical advantage=load/effort

There is no formula to calculate the length of a wire. The length of a wire is determined by the distance from the power source to where the load is situated.

Load Bearing - something that bears a load. Like a load bearing wall in a house. The wall is holding something up like the roof, another floor, etc.

38 feet longIt is not possible to give a definite answer without more detail. The construction and type of roof will determine the load (weight) bearing on the beam, and factors such as wind load and earthquake load, and the way the roof bears on the beam (truss/point load/distributed load) will all affect the sizing.

Usually, a load bearing wall will be perpendicular to the roof ridge.
