WebSep 16, 2024 · Describe how a screw and nut move in relatively opposite directions. A power screw (also sometimes called a lead screw) is another simple machine that is essentially the surface of a wedge wound around a shaft. A power screw assembly includes a nut that is machined to fit around the screw. WebFriction. Friction is the contact resistance exerted by one body when the second body moves or tends to move past the first body. Friction is a retarding force that always acts opposite to the motion or to the tendency to move.

WebIs it possible for friction to be more then 49N. For example the ramp can hold the wood block but also can hold a heavier car. If yes, does a ramp have a certain amount of total friction and only uses a little for smaller objects and more for bigger objects until you have an object with an Fg parallel which exceeds the capacity of the max amount of friction … WebJul 28, 2024 · Friction in Flat Belts. A flat belt is any system where the pulley or surface only interacts with the bottom surface of the belt or cable. If the belt or cable instead fits into a groove, then it is considered a V belt.
