Title: How do I calculate the torque required to rotate a cube? Post by: ild on Oct 17, 2012 It depends on the point about which the cube is rotated
torque= moment of inertia x angular acceleration if u are rotatin it about the the centre of mass with the axis of rotation perpendicular to the face of the cube... then the moment of inertia = 1/6 m x a x a (a=edge length of the cube, m=mass).as the axis of rotation changes the moment of inertia of the cube changes and hence the torque required to produce a particular angular acceleration changes. |
