Assessment Brief
Q1: The block brake is used to stop the wheel from rotating when the wheel is subjected to a couple moment Mo = 360 Nm. If the coefficient of static friction between the wheel and the block is 0.6, determine the smallest force P that should be applied. Find the smallest P once again, for the case when the couple moment Mo is reversed and becomes counterclockwise. Q2: Determine the smallest force P that must be applied in order to the cause the 150lb uniform crate to move (tip/slide). The coefficient of static friction between the crate the floor is 0.5. If the weight of the man is 150lb and the coefficient of static friction between his feet and ground is 0.2, will he be able to move the crate?
