Theory of machines - Section 1 (6)

The partial balancing of reciprocating parts in locomotives produces

The factor which affects the critical speed of a shaft is

When the relation between the controlling force (F_c) and radius of rotation (r) for a spring controlled governor is F_c = ar + b, then the governor will be

In a circular arc cam with roller follower, the acceleration in any position of the lift will depend only upon

If ω/ω_n is very high for a body vibrating under steady state vibrations, the phase angle for all values of damping factors, will tend to approach

In a coupling rod of a locomotive, each of the four pairs is a __________ pair.

For high speed engines, the cam follower should move with

In a vibrating system, if the actual damping coefficient is 40 N/m/s and critical damping coefficient is 420 N/m/s, then logarithmic decrement is equal to
