Question 2 The man is pushing the dresser (of uniform weight) across a laminate surface. The dresser has a weight of 80 Ib, and the coefficient of friction, µ, = 0.25. If the man pushes in the direction 30 2m shown. a) Determine the smallest force F 1.5m necessary to slide the dresser. (slipping). Fs=22016 b) Determine the smallest F necessary to tip the dresser. F;= 267.5 Hb c) Which way will the dresser move first? d) The man has a weight of 150 lb. given the answer to part a and b, determine the minimum coefficient of friction between the man's shoes and the floor so that he doesn't slip. Ms= 0.17}

Clutches, Brakes, Couplings, and Flywheels

The clutch is described as a machine element used to connect or disconnect two shafts together to transmit torque or power. The clutch works on the principles of friction. The clutch is commonly used in automobiles to transfer power from the driving shaft to the driven shaft.
