The ratio of the actual damping coefficient to the critical damping coefficient is called damping factor.
If ω/ωn is very high for a body vibrating under steady state vibrations, the phase angle for all values of damping factors, will tend to approach
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)
In railway axle boxes, the bearing used is
In order to give the primary balance of the reciprocating parts of a multi-cylinder in-line engines,
When a particle moves round the circumference of a circle of radius r with ω rad/s, then its maximum acceleration is ω2r.
The centre distance between two meshing involute gears is equal to
The frictional torque transmitted in a multi-collared shaft is same as that of a single collared shaft.
