Design a quadruple-dwell cam with the following properties: • Dwell at 0mm for 30° • Rise to 10mm over 40° and dwell for 30° • Rise to 15mm over 20° and dwell for 60° • Fall to 10mm over 40° and dwell...

Design a quadruple-dwell cam with the following properties:

• Dwell at 0mm for 30°

• Rise to 10mm over 40° and dwell for 30°

• Rise to 15mm over 20° and dwell for 60°

• Fall to 10mm over 40° and dwell for 60°

• Fall back to 0mm over 80°

Use a 3-4-5 polynomial and plot the cam profile and s-v-a-j diagram for the cam. The base radius is 50mm and the cam rotates at 2000rpm. What is the peak acceleration for this cam?
