## Theory of Machine The component of the acceleration, parallel to the velocity of the particle, at the given instant is called

Tangential component
Coriolis component
None of these

## Theory of Machine A rotor which is balanced statically but not dynamically is supported on two bearings L apart and at high speed of the rotor, reaction on the left bearing is R. The right side of the bearing is shifted to a new position 2L apart from the left bearing. At the same rotor speed, dynamic reaction on the left bearing in the new arrangement will

Become equal to R/4
Become equal to 2R
Become equal to R/2
Remain same as before

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

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

## Theory of Machine In elliptical trammels

One pair turning and three pairs sliding
All four pairs are turning
Two pairs turning and two pairs sliding
Three pairs turning and one pair sliding
