## Theory of Machine Bifilar suspension method is used to find the

Moment of inertia of the body
Angular acceleration of the body
Periodic time of the body
Frequency of vibration of the body

## Theory of Machine A motor car moving at a certain speed takes a left turn in a curved path. If the engine rotates in the same direction as that of wheels, men due to centrifugal force

The reaction on the rear wheels increases and on the front wheels decreases
The reaction on the outer wheels increases and on the inner wheels decreases
The reaction on the front wheels increases and on the rear wheels decreases
The reaction on me inner wheels increases and on the outer wheels decreases

None of these
The net dynamic force acting on the shaft is equal to zero
