A slender rod 6ft. long rotates about an axis perpendicular to it at at a point 2ft. from one end. The rod weighs 40 lb. Compute the moment of inertia about the axis of rotation.

A light, slender rod has two point masses attached at each end. The rod is thrown into the air by a person so that it is moving away from him and spinning at the same time. In such a case, the rod will be spinning about its center of mass. If the rod is spinning such that it makes one complete turn in time 'T', what is its rotational kinetic energy? Given: Mass of rod = negligible, point mass 1 = M1 = 2.8 kg, point mass 2 = M2 = 3.8 kg, length of rod = L = 1.5 m, makes one turn in time T = 0.8 s. Write your answer in joules.

A uniform rod of mass 8.5 kg and length 7.4 m is free to rotate about one end (see the following figure). If the rod is released from rest at an angle of 60° with respect to the horizontal, what is the speed (in m/s) of the tip of the rod as it passes the horizontal position?

00:01 All right, so let's say we have a rod with a length of 6 feet and a weight of 40 pounds, and it's rotating about a point that is 2 meters from the end.
00:13 So we want to calculate the moment of inertia here.
00:16 So we'll have to use the parallel axis theorem to do this.
00:21 So we know that the moment of inertia is going to be the moment of inertia about like the center of mass plus the mass of the rod, or in this case the weight of the rod, times the distance it's shifted from the center of mass.
00:37 So this will be l over 2 minus d squared...
