The equation for the acceleration is:
•The acceleration is a maximum at θ/β=0
•The acceleration is a minimum at θ/β=1
•The velocity is a maximum at θ/β=0.50
•The curves are symmetrical; therefore the displacement at θ/β=0.50 is 1/2 of the total.
•The velocity curve has zero slope at θ/β=0.5. This means the acceleration is zero at this point.
•The displacement has zero slope at θ/β=0 and θ/β=1. This means the velocity is zero at these points.
•Acceleration of the follower is required to increase the velocity from zero and deceleration is required to reduce the velocity from a non-zero value. This is true whether the resulting velocity is positive or negative.
1.These curves are drawn for a positive displacement of the follower. A negative displacement will result in a mirror image of the graphs about the x-axis.
2.The X axis is θ/β from 0 to 1
3.The Y axis is based on a displacement of 1.
