A window cleaner is pulling himself up to a pulley that consists of two disks welded together as shown. The person is currently pulling straight down on the rope in his hands with a force of magnitude 580.4 N. The other rope is also vertical and is attached to the person's center of mass. The person's mass is 74.2 kg, the pulley's total moment of inertia is 395 kgm2, the radius of the small disk is 0.39 m, and the radius of the big disk is 0.73 m. What is the magnitude of the acceleration of the person's center of mass?

A shaft is supported in bearings 1.8 m apart and projects 0.45 m beyond bearings at each end. The shaft carries three pulleys, one at each end and one at the middle of its length. The mass of end pulley is 48 kg and 20 kg and their center of gravity are 15 mm and 12.5 mm respectively from the shaft axis as shown in Figure Q3. Given that B has a mass of 56 kg, center of gravity 15mm and its position is on the middle between bearing L and M. If the pulleys are arranged so as to give static balance and by taking bearing L as reference plane, determine a. the relative angular positions of the pulleys b. the dynamics forces produced on the bearings when the shaft rotates at 300 rpm
