Please write your homework neatly. Don't try to cram all the problems into the
minimum space. Show your work clearly, and useful diagrams are always appropriate
and may get extra points. You may work with others, but the work should be your
own. I expect numeric answers to have a reasonable number of significant figures
and proper units.
1. Write out your solution for #6. HRW6 11.P.031 on the WebAssign Problem
Set 1.0 rotn motion.
| 2. A pendulum is made from a thin cylindrical rod (length L, radius
r) and a solid ball (Radius R) as shown. Each part has a mass M. The pendulum
is pivoted from the axis shown, held so that the rod is horizontal, and
released from rest. (a) Find the moment of inertia of the pendulum (use the tables in the text) in terms of M, R, r, g, and L. (b) Find the location of the center of mass, relative to the axis of rotation, in terms of M, R, r, g, and L. (c) Find the angular velocity of the pendulum when it reaches its lowest position in terms of M, R, r, g, and L. [Hint: Energy.] |
