## Theory of Machine Tangential acceleration direction is

Opposite to angular velocity
Along the angular velocity
Perpendicular to angular velocity
May be any one of these

## Theory of Machine The Bifilar suspension method is used to determine

Natural frequency of vibration
Moment of inertia
Position of balancing weights
Centripetal acceleration

## Theory of Machine The sense of Coriolis component is such that it

Leads the sliding velocity vector by 180°
Leads the sliding velocity vector by 90°
Is along the sliding velocity vector
Lags the sliding velocity vector by 90°

## Theory of Machine When a slider moves on a fixed link having curved surface, their instantaneous centre lies

On their point of contact
At the pin joint
At the centre of circle
At the centre of curvature

## Theory of Machine In locomotives, the ratio of the connecting rod length to me crank radius is kept very large in order to

Minimize the effect of primary forces
To start the locomotive quickly
Minimize the effect of secondary forces
Have perfect balancing

## Theory of Machine The frictional torque transmitted by a cone clutch is same as that of

Flat pivot bearing
Flat collar bearing
Truncated conical pivot bearing
Conical pivot bearing
