Axis of Rotation and Moment of Inertia Ranking Task
Axis of Rotation and Moment of Inertia Ranking Task Two identical uniform solid spheres are attached by a solid uniform thin rod, as shown in (Figure 1). The rod lies on a line connecting the centers of mass of the two spheres. The axes A, B, C, and D are in the plane of the page (which also contains the centers of mass of the spheres and the rod), while axes E and F (represented by black dots) are perpendicular to...

Determine the moment of inertia of a uniform cube when the rotation axis is along an edge. Suppose its total mass is M=2.5kg, the edges are each 10.0 cm long, it begins at rest, and a constant force, F=4.0N is applied to the edge diagonally opposite the rotation axis. The moment arm and the force are at an angle of 60 degrees. What would its angular displacement from the start be when its angular velocity is 13 rad/s? Draw the...
