Question #7554

2 small weights of M1=5-Kg. and M2=7-Kg. are mounted 4cm apart on a light rod as shown. The moment of inertia of the system

a. if rotated about the axis half between weights.

b. if rotated about the axis 0.50cm left of 7-Kg.mass

*There are 3 equations for the rod figure on our workbook. I don't know what to use.*

1. I center = mL^2/12

2. I end = mL^2/3

3. I = mR^2
