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

Sliding pair
Turning pair
Spherical pair
Screw pair

√(3m/T)
T/3

## Theory of Machine Torsional vibrations are said to occur when the particles of a body moves

In a circle about its axis
None of these
Perpendicular to its axis
Parallel to its axis

## Theory of Machine If the damping factor for a vibrating system is unity, then the system will be

Critically damped
Under damped
Over damped
Without vibrations

## Theory of Machine The pair is known as a higher pair, when the relative motion between the elements of a pair is

Rolling only
Sliding only
Partly turning and partly sliding
Turning only
