## Theory of Machine The Coriolis component of acceleration exists whenever a point moves along a path that has

Linear displacement
Rotational motion
Tangential acceleration
Gravitational acceleration

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

Coriolis component
None of these
Tangential component

## Theory of Machine The velocity of piston in a reciprocating steam engine is given by (where ω = Angular velocity of crank, r = Radius of crank pin circle, θ = Angle turned by crank from inner dead center, and n = Ratio of length of connecting rod to the radius of crank)

ω²r [cos θ + (cos 2θ/n)]
ωr [sin θ + (sin 2θ/n)]
ωr [cos θ + (cos 2θ/n)]
ω²r [sin θ + (sin 2θ/n)]

## Theory of Machine When the particles of a body moves perpendicular to its axis, then the body is said to have
