No hint provided
Question 5.
Design a circular arc cam that will provide a follower motion of 2 inches over a complete rotation with a pressure angle not exceeding 20 degrees. Discuss considerations you have to keep in mind.
Show hintHide hint
Think about the relationship between cam radius and pressure angles.
Question 6.
Given a follower with known dimensions, calculate the effect of increasing the pressure angle from 10 to 30 degrees on the contact forces experienced by the cam.
