Cable trays are used as an alternative to open wiring or electrical conduit systems, and are commonly used for cable management in commercial and industrial construction.
Static friction must be overcome. Once a force has been applied that starts the object in motion, the force of kinetic friction is less than its static counterpart. 1 person found this useful. Edit.
Kinetic friction is involved any time an object is moving up or down a ramp.. You can solve problems with kinetic friction as easily as those that involve static friction.f she has a mass of 30.0 kg and the coefficient of kinetic friction is 0.10, how much force will you need to apply to keep her going? Youâre pushing a box of books with a mass of 25 kg up a 40-degree ramp.
