## Theory of Machine Whirling speed of the shaft is the speed at which

Shaft tends to vibrate in longitudinal direction
Torsional vibrations occur
Combination of transverse and longitudinal vibration occurs
Shaft tends to vibrate vigorously in transverse direction

## Theory of Machine The Klein's method of construction for reciprocating engine mechanism

Utilizes a quadrilateral similar to the diagram of mechanism for reciprocating engine
Is a simplified form of instantaneous center method
Is based on acceleration diagram
Enables determination of Cariole’s component

## Theory of Machine If some links are connected such that motion between them can take place in more than one direction, it is called

Incompletely constrained motion
Partially constrained motion
Completely constrained motion
Successfully constrained motion

## Theory of Machine The motion of a shaft in a circular hole is an example of

Completely constrained motion
Incompletely constrained motion
Successfully constrained motion
