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 uniform solid disc, whose moment of inertia is unknown, is rotating at an angular velocity...
A uniform solid disc, whose moment of inertia is unknown, is rotating at an angular velocity of 500 rpm. Later it falls on another solid disc that is at rest and that its moment of inertia is of 2.50 kg * m2. The final speed with which both rotate is 170 rpm. Determine the moment of inertia of the disc.
