## Theory of Machine In a mechanism, usually one link is fixed. If the fixed link is changed in a kinematic chain, then relative motion of other links

Will remain same
Will not occur
Will change
Could change or remain unaltered depending on which link is fixed

## Theory of Machine Klein's construction can be used when

Crank has non-uniform velocity
Crank has a uniform angular velocity
Crank has uniform angular velocity and angular acceleration
Crank has uniform angular acceleration

## Theory of Machine The centre of gravity of a coupler link in a four bar mechanism will experience

No acceleration
Both linear and angular acceleration
Only linear acceleration
Only angular acceleration

Zero
Minimum
Maximum
None of these

## Theory of Machine An involute pinion and gear are in mesh. If both have the same size of addendum, then there will be an interference between the

Tip of the gear tooth and flank of pinion
Tip of the pinion and flank of gear
Flanks of both gear and pinion
Tip of both gear and pinion

## Theory of Machine The example of rolling pair is

Ball bearing and roller bearing
