Plot the tangent circle and unit normal at the point of minimum radius of curvature in Problem 10.5.

Problem 10.5

Design a double-dwell cam with the following properties

• Dwell at 0mm for 90°

• Rise to 20mm over 90° and dwell for 90°

• Fall back to 0mm over 90°

The base radius is 100mm and the rise function is a 3-4-5 polynomial. Plot the radius of curvature for the cam profile. What is the minimum radius of curvature?
