Question

A single mass defect needs to be balanced by a single balancing mass

(a) True

(b) False

I had been asked this question in an international level competition.

I would like to ask this question from Balancing of a Single Rotating Mass By Two Masses Rotating in Different Planes in division Balancing of Rotating Masses of Machine Dynamics

Answer 1

The correct choice is (b) False

For explanation I would say: A single mass defect lying on a single plane can be countered with the help of different masses lying on different planes with the defective mass either being at center or to the either side.
