(Figure 1) A thin rod of mass mr and length 2L is allowed to pivot freely about its center, as shown in the diagram.
Pivoted Rod with Unequal Masses (Figure 1) A thin rod of mass mr and length 2L is allowed to pivot freely about its center, as shown in the diagram. A small sphere of mass m1 is attached to the left end of the rod, and a small sphere of mass m2 is attached to the right end. The spheres are small enough that they can be considered point particles. The gravitational force acts downward, with the magnitude of the gravitational acceleration...

1. A uniform rod of mass M = 5.01kg and length L = 1.18m can
pivot freely (i.e., we ignore friction) about a hinge attached to a
wall, as seen in the figure below.
2. Determine the linear acceleration of the tip of the rod.
Assume that the force of gravity acts at the center of mass of the
rod, as shown.

a) Calculate the electrostatic force on a uniformly charged rod of length 2l,and charge q which lies along the axis of a uniformly charged ring of radius R and charge q'. The centers of the charged rod and the rings are displaced by z = z0 . (b) Show that if z0 >>l,is satisfied, then the expression of calculated force reduces to that between point charges.

A thin rod of mass M and length L has a fixed rotation axis a distance L/6 from one end. (a) Using the parallel-axis theorem, find the moment of inertia of the rod about its rotation axis. (b) Suppose the rod is held horizontally at rest and then released. Draw a free-body diagram of the rod at the moment of its release, and find its angular acceleration at this moment. (Remember that gravity acts at the rod’s center.) (c) Find...
