Question #198985

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 45Â° 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]**
