1. The 20-kg flywheel has a radius of gyration kg = 0.5 m about the axis of its attached shaft (O-0). It is at rest when subjected to a torque that rises uniformly from 0 to 2 N-m over 3 revolutions, then holds at a constant 2 N-m for the remainder of the motion. What is the angular velocity of the flywheel after 10 revolutions? Give your answer in RPM.

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.
The 17-kg wheel is rolling under the constant moment of M = 85 N-m. The wheel has radius r= 0.50 m, has mass center at point G, and the radius of gyration is kg = 0.20 m.

A ring of mass m =1 kg and radius R = 1m is attached to a vertical shaft by means of a frictionless pin. Coordinates xyz are fixed to the ring as shown and the frictionless pin at A is aligned with the x-axis. The vertical shaft precesses about the Z-axis with constant angular velocity 2 = 1 rad/s. (a) At a particular moment when 0 = 30° and = 4 rad/s, find the value of Ö . This comes from a sum of the moments about the x-axis. Do not neglect gravity. (b) Find the torque or moment necessary that must be applied about the vertical shaft in order to keep it turning at a constant rate of N = 1 rad/s. Ring R XG A 1 Ixx = lyy =mR? G Iz = mR?
2. Consider the 5-1lb bar with length of 2½ feet and width of 2 inches. Small frictionless bearings are mounted to the ends, constraining the motion of the bar to the horizontal x and y slots. The bar starts at rest at positioned at 0= 45°. If an angular acceleration of 3 rad/s² is desired, what moment M must be applied to the bar? What are the reaction forces at A and B at that instant? Additional question: Does the width of the bar matter, or is it appropriate to consider the bar as a slender rod? Consider errors of less than 2% negligible.
