A torque T = 0.30 N-m is applied to a bevel gear B. Bevel gear D meshes with gear B and drives pump A. Gear B has a radius of gyration of 150 mm and a weight of 50 N, whereas gear D and the im- peller of pump A have a combined radius of gy- ration of 50 mm and a weight of 100 N. Find how many revolutions of gear B are needed to get the pump up to 200 rpm from rest. What is the power output of the pump at this speed if it is 90% efficient.
