Therefore, a good strategy is to calculate the moment of inertia of the threerods system about the y-axis and use the parallel axis theorem to determine the moment of inertia about the given axis. A Kinetic energy can be measured in watts. As shown in thefigure, the hole does not pass through the center of the disk. Calculate the final angular speed of the discus. Assume the wheel has a constant negative angular acceleration of magnitude 1. Rotational Motion Lab 7: Find its moment of inertia for rotation on its hinges.

The trebuchet-earth system should preserve its mechanical energy. The frictionless motion of the system guarantees energy conservation: The final angular speed is again related to the final linear speed as:

On page of Giancoli, problem Unit 4 Practice Test: The cam with the hole cut out has mass M. A simple trebuchet is shown in the figurebelow. The net torque must be changing solutionn a maximum when the arm of thetrebuchet is horizontal and going to zero as it stands 11. The cam is mounted on a uniform,solid, cylindrical shaft of diameter R and also of mass M.
