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.

Angling for a New Idea Conservation of L A) I Spin while holding two dumbbells close to your body with your arms folded, spin around on the ro- tating chair (be sure your feet are not touching the chair or ground). Next quickly push the dumbbells straight out to arm's length When you moved the dumbbells away from your trunk, was there a net torque applied to the system (you + rotating chair + dumbbells)?

A wheel-axle assembly is attached to a spring as shown in the figure below. The wheel-axel assembly has a mass of m=3 kg and a radius of gyration about the polar axis of kG=75mm. The spring has a stiffness of k=0.5 kN/m ( Note the units!). The system is released from rest with a spring extension of x1=0.2 m. Calculate the maximum angular velocity. Assume friction can be ignored. Provide your answers in rad/s.

A child pushes her friend (m = 25 kg) located at a radius r = 1.5 m on a merry-go-round (rmgr = 2.0 m, Imgr = 1000 kg*m2) with a constant force F = 90 N applied tangentially to the edge of the merry-go-round (i.e., the force is perpendicular to the radius). The merry-go-round resists spinning with a frictional force of f = 10 N acting at a radius of 1 m and a frictional torque τ = 15 N*m...
