Recently I have developed an interest in NASA's Advanced Resistive Exercise Device(ARED) because of its ability to apply an almost constant resistance in normal and microgravity. For anyone who isn't familiar with it, here is a link to learn more about it:

I have found that the ARED...
Do electric hoist/lift motors apply a constant force to the weight they are lifting? What would happen if the force translated from the motor torque was the same as the weight of the object at a position off the ground? In other words, the force pointing up is equal to the weight pointing down...
I am working on a project to support a large pipe during thermal expansion. Most of the weight will be supported from the top, but a constant portion of the weight needs to be supported from the bottom to minimize permanent thermal expansion without causing a buckle at the top. I originally...
