A counterclockwise torque is suddenly applied to a rotating shaft with a moment of inertia of 5 kg•m2 . The shaft was initially at rest (zero speed). If the applied torque causes the shaft to rotate at a constant angular acceleration of 1.5 rad/s2 , considering zero viscous damping: a) Calculate the applied torque. b) Calculate the angular speed of the shaft after 5 seconds in radians per second. c) Express the speed in revolutions per minute.

A flywheel has a moment of inertia of 210 kg · m2 and the speed of 600 rpm. An aggregate is connected to the wheel with the moment of inertia 70 kg · m2. Calculate the system's new speed. How many percent of it original mechanical energy has the flywheel left after the connection? ( Answer 450 rpm; 75%)
A torque of 35.9 N · m is applied to an initially motionless wheel which rotates...
A torque of 35.9 N · m is applied to an initially motionless wheel which rotates around a fixed axis. This torque is the result of a directed force combined with a friction force. As a result of the applied torque the angular speed of the wheel increases from 0 to 10.3 rad/s. After 6.20 s the directed force is removed, and the wheel comes to rest 60.2 s later. (a) What is the wheel's moment of inertia (in kg...

A torque of 35.9 N · m is applied to an initially motionless wheel which rotates around a fixed axis. This torque is the result of a directed force combined with a friction force. As a result of the applied torque the angular speed of the wheel increases from 0 to 9.7 rad/s. After 6.10 s the directed force is removed, and the wheel comes to rest 60.2 s later. (a) What is the wheel's moment of inertia (in kg...
