The 40-kg wheel has a radius of gyration about its center of gravity G of k_G = 250 mm. If it rolls without slipping, determine its angular velocity when it has rotated clockwise 90 degree from the position shown. The spring AB has a stiffness k = 100 N/m and an unstretched length of 500 mm. The wheel is released from rest.

2. An unknown mass is attached via string to the axle (radius 0.20 m) of wheel (radius 0.40 m). The wheel has moment of inertia 0.053 kg m2. When the system is released from rest, the mass accelerates downward at 0.10 m/s. a) What is the mass? b) How fast is the mass moving if it falls 1.0 m? Hint: use kinematics. c) What is the total kinetic energy of the system at that location? 3. Reconsider the previous scenario...

The 50-kg flywheel has a radius of gyration about its center of
mass of ko= 250mm. It rotates with a constant angular velocity of
120rev/min before the brake is applied. If the coefficient of
kinetic friction between the brake pad B and the wheel’s rim is ?k=
0.5, and a force of P = 300 N is applied to the braking mechanism’s
handle, determine the time required to stop the wheel.
