Theory of machines
Mechanisms
Kinetics
Applied mechanics

## Theory of Machine A thin circular disc is rolling with a uniform linear speed, along a straight path on a plane surface. Which of the following statement is correct in this regard?

The centre of the disc has zero acceleration
All points of the disc have the same velocity
The point on the disc making contact with the plane surface has zero acceleration
The centre of the disc has centrifugal acceleration

## Theory of Machine A system in dynamic balance implies that

There is no critical speed in the system
The system is critically damped
The system is also statically balanced
There will absolutely no wear of bearings

## Theory of Machine A system of masses rotating in different parallel planes is in dynamic balance if the

Resultant force is numerically equal to the resultant couple, but neither of them need necessarily be zero
Resultant force is equal to zero
Resultant couple is equal to zero
Resultant force and resultant couple are both equal to zero
