The natural frequency of free torsional vibrations of a shaft is equal to (where q = Torsional stiffness of the shaft, and I = Mass moment of inertia of the disc attached at the end of a shaft)
-
If the rotating mass of a rim type flywheel is distributed on another rim type flywheel whose mean radius is half the mean radius of the former, then energy stored in the latter at the same speed will be
-
The Grubler's criterion for determining the degrees of freedom (n) of a mechanism having plane motion is (where l = Number of links, and j = Number of binary joints)
-
In a Hartnell governor, if a spring of greater stiffness is used, then the governor will be
-
The included angle for the V-belt is usually
-
When two pulleys are connected by means of an open belt drive, then both the pulleys will rotate is opposite directions.
-
The amplitude of vibration is always __________ the radius of the circle.
-
An involute pinion and gear are in mesh. If both have the same size of addendum, then there will be an interference between the
-
In vibration isolation system, if ω/ωn > 1, then the phase difference between the transmitted force and the disturbing force is
