Assignment 31

The study of angular dynamics continues.  Moments of inertia are calculated.  Angular momentum is introduced.

The qa assignment is focused on torques and their effect on rotational motion.

The lab exercise is to view and experiment and understand how the velocity of descent of a mass supported by a string around the axel of a disk is proportional to angular velocity of disk.

Class Notes topics include

• calculation of moment of inertia
• moments of inertia for common objects
• statics and dynamics of cantilevered beam
• leaning ladder
• introduction to simple harmonic motion

The text assignment addresses moment of inertia, rotational dynamics and angular momentum.
