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

Along perpendicular to angular velocity
Along tangential acceleration
Along the centripetal 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

Bevel gearing
Helical gearing
Spur gearing
Spiral gearing

## Theory of Machine The sense of Coriolis component 2 ωv is same as that of the relative velocity vector v rotated at

90° in the direction of rotation of the link containing the path
180° in the direction opposite to the rotation of the link containing the path
45° in the direction of rotation of the link containing the path
45° in the direction opposite to the rotation of the link containing the path

## Theory of Machine Idler pulley is used

For increasing velocity ratio
For applying tension
All of the listed here
For changing the direction of motion of the belt

## Theory of Machine When a rigid body is suspended vertically and it oscillates with a small amplitude under the action of the force of gravity, the body is known as

Second's pendulum
Simple pendulum
Torsional pendulum
Compound pendulum
