A rope supporting a mass passes around four simple frictionless pulleys at points A, B, C and D, and around two fixed drums at points E and F. The mass exerts a force of 1000 N on the rope. The radius of all pulleys and drums is 75 mm. If the coefficient of friction between the rope and all the surfaces it contacts is 0.3, what is the minimum force, P, necessary to hold the weight in position?

A crate with a weight of 100 N is sitting on top of a crate weighing 200 N. The rope that joints the crates passes around a frictionless pulley at A and a fixed drum at B. If the coefficient of friction is H 0.30 at all surfaces, determine the minimum force P required to start the 200 N crate moving.

1. An unknown mass (mı) on a rough horizontal surface is attached by a wire that passes over a massless, frictionless pulley to a 2.50kg mass (m2) as shown below. The bottom of the hanging mass is 1.50m above the floor. The system is released from rest at t-0s and the 2.50kg mass strikes the floor 0.82s later. The system is now returned to its initial position and a 1.20kg mass is placed on top of the block of mass...
