The crank of a slider crank mechanism is 15 cm and the connecting rod is 60 cm long. The crank makes 250 r. p.m in the clockwise direction. When it has turned an angle of 210 ϕ from the inner dead center (I. D.C) position, graphically determine:

a. Velocity of slider C

b. Angular velocity of connecting rod and

c. Linear velocity of the mid-point of the connecting rod (D).

d. Use complex number and instant center methods to check the results.

2. From the result of parts 1, graphically determine:

a. Acceleration of point C

b. Angular acceleration of connecting rod CB​
