The flywheel of an engine has a moment of inertia 2.50 kg-m² about its rotation axis. What constant torque is required to bring it up to an angular speed of 400 rpm in 8.00s, starting from rest?

The flywheel of an old steam engine is a solid homogeneous metaldisk of mass M = 118 kgand radius R = 80 cm.The engine rotates thewheel at 460 rpm. In an emergency, to bring the engine to a stop,the flywheel is disengaged from the engine and a brake pad isapplied at the edge to provide a radially inward force F = 130 N.Ifthe coefficient of kinetic friction between the pad and theflywheel is Âµk = 0.2,how many revolutions does the flywheel makebefore coming to rest?

How long does it take for the flywheel to come to rest?

Calculate the work done by the torque during this time.
