## Theory of Machine In an ideal machine, the output as compared to input is

Equal
Less
More
May be less or more depending on efficiency

## Theory of Machine A spring controlled governor is found unstable. It can be made stable by

Increasing the spring stiffness
Decreasing the ball mass
Increasing the ball mass
Decreasing the spring stiffness

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

## Theory of Machine The relation between number of links (l) and number of joints (j) in a kinematic chain is

l = (2/3).(j + 2)
l = (1/2).(j + 2)
l = j + 4
l = (3/4).(j + 3)
