Problem 1: At any instant, Pulley 1 rotates at a constant speed of 100 rpm to crush the rocks. Assuming no friction between the belt and the pulleys, and between the

eccentric shaft and the bearings, determine: (a) Angular speed of Pulley 2 (b)Normal acceleration of Flywheel (c) Angular kinetic energy of Pulley 2 and Flywheel to drive the moving jaw for crushing Problem 2: In order to start crushing operation, the motor drives the Pulley 1 to linearly accelerate from the rest to 500 rpm in 50 revolutions. Assuming no friction between the belt and pulleys, and between the eccentric shaft and the bearings, and the moment of inertia of the rotating system is 2.51 kg-m². Determine: (a) required torque and power of the motor (b) angular kinetic energy of Pulley 2 and Flywheel after 50 revolutions
