Answer: C :Both (a) and (b)
For dynamic balancing of a shaft, the net dynamic force acting on the shaft is equal to zero, and the net couple due to the dynamic forces acting on the shaft is equal to zero.
A system is said to be dynamically balanced if two conditions are satisfied.
- The resultant of all the dynamic forces acting on the system during rotation must be zero.
- The resultant couple, due to all the dynamic forces acting on the system during rotation, about any plane, must be zero.
Hence, option c is correct.
