## Theory of Machine Klein's construction is useful to determine

Angular acceleration of various parts
Velocity of various parts
Displacement of various parts
Acceleration of various parts

## Theory of Machine The direction of Coriolis component of acceleration is the direction

Along the centripetal acceleration
Along tangential acceleration
Of relative velocity vector for the two coincident points rotated by 90° in the direction of the angular velocity of the rotation of the link
Along perpendicular to angular velocity

360°
180°
90°

None of these
Unstable
Isochronous
Stable

## Theory of Machine In a radial cam, the follower moves

In any direction irrespective of the cam axis
In a direction parallel to the cam axis
In a direction perpendicular to the cam axis
Along the cam axis

## Theory of Machine The static balancing is satisfactory for low speed rotors but with increasing speeds, dynamic balancing becomes necessary. This is because, the

Unbalanced couples are caused only at higher speeds
Unbalanced forces are not dangerous at higher speeds
Effects of unbalances are directly proportional to the speed
Effects of unbalances are proportional to the square of the speed
