Cable spreading room at Point Tupper. In the electrical wiring of buildings, a cable tray system is used to support insulated electric cables used for power distribution and communication. 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.
Although this force is the smallest, it still can be a factor when the other causes of friction are low. Types of friction . There are two main types of friction: static and kinetic. Static friction is the amount of resistance to motion when an object is static or not moving. Kinetic friction is the resistance on a moving object. Kinetic friction is further classified as sliding or rolling friction.
