In a slider crank mechanism, the length of crank OB and connecting rod AB are 125 mm and 500 mm respectively. The centre of gravity G of the connecting rod is 275 mm from the slider A. The crank speed is 600 r.p.m. clockwise. When the crank has turned 45° from the inner dead centre position, determine:
1. velocity of the slider A,
2. velocity of the point G, and
3. angular velocity of the connecting rod AB. Use relative velocity method.
[Ans. 6.45 m/s ; 6.75 m/s ; 10.8 rad/s]
