Q$.3$ A small connecting rod $220$ mm long between centers has a mass of $2$ kg and moment of

inertia of $2{10}^{4}kg-m{m}^2$ about its centre of gravity. Centre of gravity is located at a

Page $1$ of $2$

distance of $150$ mm from the small end centre, Determine the dynamically two$-$mass

system when one mass is located at the esmall end. Deentre. If the the onnnecting rod is replaced

by two masses located at the two centers, find the correction couple that must be applied

for complete dynamical equivalence of the system, when the angular acceleration of the

connecting rod is $20000ra\frac{d}{s^2}$ clockwise.
