Question 1.
What is the pressure angle in cam design?
Show hintHide hint
Think about how the motion of the follower relates to the cam's shape.
Question 2.
Define undercutting in cam profiles.
Show hintHide hint
Consider how cutting affects interaction between moving parts.
3Question 3.
What is the main impact of a high pressure angle?
- Reduces wear
