A bead of mass M is able to move without friction along a stationary horizontal rod...
A bead of mass M is able to move without friction along a stationary horizontal rod (directed along the x axis). In addition, a second body of mass m is attached to the first bead and suspended below it via a massless rod of length a. This second mass and rod form a pendulum that is able to swing in the xy-plane (where y is the vertical axis). (a) Obtain the Lagrangian for the system of two masses. (b) Assuming...

A rod of mass M and length 2L is free to rotate in a vertical plane about an axis through O, as shown in the figure. The axis is normal to the plane of the paper. Three mosses M, M, and 2M are attached to the rod as shown. With the rod in a horizontal position, the system is released from rest. (a) Find the net torque on the rod about the axis of rotation immediately after the system is...

4. A rod AB of mass M and length L is free to rotate about a horizontal axis through A. The rod is held horizontal and the endB is released. The rod rotates about A, and when it is vertical, the end B collides with a small mass M/2 and the mass gets attached to the rod. In the Sbsequent motion,...

The figure shows a rigid
assembly of a thin hoop (of mass m = 0.27 kg and radius R = 0.17 m)
and a thin radial rod (of length L = 2R and also of mass m = 0.27
kg). The assembly is upright, but we nudge it so that it rotates
around a horizontal axis in the plane of the rod and hoop, through
the lower end of the rod. Assuming that the energy given to the
assembly in...

The figure shows a rigid structure consisting of a circular hoop of radius R and mass m, and a square made of four thin bars, each of length R and mass m. The rigid structure rotates at a constant speed about a vertical axis, with a period of rotation of 4.3 s. If R = 1.1m and m = 1.8 kg, calculate the angular momentum about that axis.
