Whitworth quick return motion mechanism consists of three turning pairs and one sliding pair.

The frequency of damped vibrations with viscous damping is __________ the frequency of undamped vibrations.

The gears are termed as medium velocity gears, if their peripheral velocity is

When the crank is at the inner dead centre, in a reciprocating steam engine, then the velocity of the piston will be

The radial distance of a tooth from the pitch circle to the bottom of the tooth is called

The tractive force in a locomotive with two cylinders is given by (where c = Fraction of reciprocating parts per cylinder, m = Mass of reciprocating parts, ω = Angular speed of crank, r = Radius of crank, and θ = Angle of inclination of crank to the line of stroke)

The steering of a ship means
