## Theory of Machine Angle of action of cam is defined as the angle

Moved by the cam from beginning of ascent to the termination of descent
Through which the cam rotates during the period in which the follower remains in the highest position
Of rotation of the cam for a definite displacement of the follower
Moved by the cam from the instant the follower begins to rise, till it reaches its highest position

## Theory of Machine The example of completely constrained motion is a

All of these
Motion of a shaft with collars at each end in a circular hole
Motion of a piston in the cylinder of a steam engine
Motion of a square bar in a square hole

Less than
Equal to
None of these

## Theory of Machine A reed type tachometer use the principle of

Transverse vibration
Damped free vibration
Longitudinal vibration
Torsional vibration

## Theory of Machine When the belt is stationary, it is subjected to some tension known as initial tension. The value of this tension is equal to the

Sum of the tensions on the tight side and slack side of the belt
Tension in the slack side of the belt
Average tension of the tight side and slack side of the belt
Tension in the tight side of the belt
