Mechanical Engineering Problems on Torque and Friction by Sai Smart is a document available to read on EtoBox.
1) A screw jack raises a 16 kN load 150 mm. The screw has a 56 mm diameter and 10 mm pitch. The problem determines the work done and efficiency when the load rotates with the screw, with a friction coefficient of 0.11. 2) A differential band brake on a 800 mm drum applies a 500 N force at 800 mm from the fulcrum, with a 2700 contact angle and 0.23 friction. The problem finds the brake torque. 3) Thrust bearing problems involve calculating power lost to friction and number of collars needed, given radii, lo
