Question

A hollow cylinder, of inner radius 0.28m and outer radius 0.41m, is rotating around an axis through the center like a wheel. What would be the torque experienced if it has a mass of 4.00kg and an angular acceleration of 11.11rad/s²?

Definition Definition Rate of change of angular velocity. Angular acceleration indicates how fast the angular velocity changes over time. It is a vector quantity and has both magnitude and direction. Magnitude is represented by the length of the vector and direction is represented by the right-hand thumb rule. An angular acceleration vector will be always perpendicular to the plane of rotation. Angular acceleration is generally denoted by the Greek letter α and its SI unit is rad/s 2 .
