A 5kg bag is gently pushed off the top of a wall and swings in a vertical plane at the end of a 2.4 m rope which can withstand a maximum tension fm. For fm 40t0140 use computational software to determine the difference in elevation h between point a and point b where the rope will break

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.
