## Theory of Machine In multi V-belt transmission, if one of the belt is broken, we have to change the

There is no need of changing any one as remaining belts can take care of transmission of load
Broken belt and its adjacent belts
Broken belt
All the belts

## Theory of Machine A body is said to be under forced vibrations, when

A body vibrates under the influence of external force
There is a reduction in amplitude after every cycle of vibration
None of these
No external force acts on a body, after giving it an initial displacement
