DESIGN OF MACHINERY SOLUTION MANUAL 8-25-1! PROBLEM 8-25Statement:Write a computer program or use an equation solver such as Mathcad or TKSolver to calculate and plot the s v a j diagrams for a 4-5-6-7 polynomial displacement cam function for any specified values of lift and duration. Test it using a lift of 20 mm over an interval of 60 deg at 1 rad/sec.Enter:Lift:h 20 mm.Duration:β60 deg.Solution:See Mathcad file P0825.1. The 4-5-6-7 polynomial is defined in local coordinates by equation 8.21.
