ME 361 Lecture Notes - Lecture 4: Outboard Motor, Angular Velocity, Drive Shaft

Which of the following speed can be associated with astronomy?

1. 80 meter/second towards the south

2. 100 light-years

3. 500 rotation per second

4. 15 light-years per 1 million years

Determine the moment of inertia of the composite area about the y axis.

Take a = 2.7in

A uniform rod is rotating on a horizontal plane about a vertical axis through one end with a constant angular velocity ω0. Due to internal shear forces, the rod breaks at the mid-point of its length, and the part with the fixed axis has an angular velocity 1.5ω0 in the same sense. Determine the angular velocity of the other half.
