A disturbing mass m‚Äö√á√Ö attached to the rotating shaft may be balanced by a single mass m‚Äö√á√á attached in the same plane of rotation as that of m‚Äö√á√Ö, such that (where r‚Äö√á√Ö and r‚Äö√á√á are the radii of rotation of m‚Äö√á√Ö and m‚Äö√á√á respectively)$

m‚Äö√á√Ö m‚Äö√á√á = r‚Äö√á√Ö r‚Äö√á√á

m‚Äö√á√Ö r‚Äö√á√á = m‚Äö√á√á r‚Äö√á√Ö

In a four-bar chain it is required to give an oscillatory motion to the follower for a continuous rotation of the crank. For the lengths of 50 mm of crank and 70 mm of the follower, determine theoretical maximum length of coupler. The distance between fixed pivots of crank and followers is
The relation l = (2/3).(j + 2) apply only to kinematic chains in which lower pairs are used. This may be used to kinematic chains in which higher pairs are used, but each higher pair may be taken as equivalent to
A rotor which is balanced statically but not dynamically is supported on two bearings L apart and at high speed of the rotor, reaction on the left bearing is R. The right side of the bearing is shifted to a new position 2L apart from the left bearing. At the same rotor speed, dynamic reaction on the left bearing in the new arrangement will
