Circular ring moment of inertia
WebThe moment of inertia of the ring is its mass times the square of its radius r, and we want to add these up for all radii from 0 to R. This means we have to do an integral I = R I 0 r 2 ä ã å å å å 2 m R 2 r dr ë í ì ì ì ì = 2 m R 2 R I 0 r 3 dr = R 2 1 4 R 4 . The result is I = 1 2 m R 2 This is an interesting result. WebThe moment of inertia of a body about a given axis is 1.2 kgm 2. Initially, the body is at rest. In order to produce a rotational kinetic energy of 1500 J, and an angular acceleration of 25 rads −2, the torque that must be applied about that axis for a duration of: Hard View solution > A thin rod of mass M and length L is bent into a circular ring.
