M 97 b b M P a a M 1. Find the moment of inertia around P 2. How much work to reach speed of 5.0 rad/s? 3. Assuming a constant torque, τ, how far did it rotate before it reached this speed? 4. Assuming a constant torque, τ, how long did it rotate before it reached this speed?

54 Find magnitude and direction of angular acceleration First find total torque

8-4 Torque The torque is defined as: (8-10a) or

54 Find magnitude and direction of angular acceleration First find total torque + Torque --- counterclockwise - Torque --- clockwise Find the moment of inertia The moment of inertia can be calculated without knowing about the torque
