R A pulley is made from two solid cylinders joined together, as shown. They rotate about an axis through their centers. In terms of the given information, what is the angular velocity of the pulley just before the 4M block hits the ground? Given information: 2T Cylinder 2 Pulley is two cylinders joined together: Cylinder 1 Cylinder 1: radius R 12R mass M thickness T Cylinder 2: radius 2R mass 2M thickness 2T 3M (mass of left block) 4M 4M...
2. A shaft carrying a 10KN load is supported by two identical plain journal bearings. The shaft, which normally rotates at 3000 rev/min has, at the bearing region, a nominal diameter of 50 mm and a length of 16 mm. Starting with a radial clearance ratio of 0.0015 and neglecting thermal effects a) Calculate the temperature of the lubricant which will produce an eccentricity ratio of 0.7 if the oil used is SAE10 b) Comment of the necessity to supply...
