Step 1

Consider the clockwise sense of rotation as positive and write the expression for magnitude of velocity of point *A* which will be directed downwards. Further, substitute suitable values to evaluate the same as:

Step 2

Now, consider the Instantaneous center of the bar AB as an arbitrary point C as shown in the figure. Write the expression for magnitude of angular velocity of the bar which will be in clockwise. Further, substitute suitable values to evaluate the same as:

Step 3

Since the crank is rotating with constant angular velocity, point *A* will only experience radial component of acceleration directed towards point *O*. Write the ex...
