1. The 60-lb flywheel has a radius of gyration about its shaft axis of ko = 15 inches. Starting at 1 = 0 with a speed of 90 rpm, the flywheel is subjected to a torque that will stop the flywheel in 10 s. The torque M ramps up from 0 to Mmax in 3 s, then holds steady at Mmar until stopped. What must be the value of Mmar?

There is a pirate ship in the harbor which features a large, cast iron wheel that is used to steer the ship. As shown in the figure above, this wheel features spokes with a length of R = 0.83 meters, configured as shown. Star symbols indicate specific points on the wheel (labelled A, B, C, D, and E). The moment of inertia of this wheel is I = 12.2 kg⋅m2.The wheel spins around a gear mechanism attached at its center. The gear mechanism has sufficient resistance (due to friction and other factors) that anyone trying to turn the wheel feels a counter-torque of τres = 10 N⋅m. After the wheel begins moving, a constant resisting torque of τres = 10 N⋅m is still felt. Someone applies a a tourque of 33.7N*mvto the wheel for five seconds, if the wheel starts at rest what is it anuglar momentum after five seconds? If the wheel is now spinning at 1 rad/sec what is the magnitude of the tourque to keep it spinning? What is the total kinetic magnitude of the wheel ( the mass is 4kg)
