Physics · Theory of Machines
The essential condition for locating two masses in order to make a rigid body system dynamically equivalent is: [where l1 & l2 = distances of the two masses from the center of gravity of the body, KG = radius of gyration of the body]
- 1l1 × l2 = KG2✓
- 2l1 + l2 = KG2
- 3l1 + l2 = KG
- 4l1 × l2 = KG
Correct answer
l1 × l2 = KG2
