Complex Engineering Problem (Mechanics of Machines)
Statement:
Write a computer solution in a programming language of your choice which would design a cam profile from a given displacement diagram data. The axis of follower and cam axis of rotation are inline. Following is input and out data requirements for the computer solution.
Input data Required output CLO Level PLO Marks
• Displacement diagram data
• Pitch circle radius • Roller’s diameter for roller follower Recognize follower’s motion type from displacement diagram data 4 C2 1 5
Diagram follower’s velocity, acceleration and jerk profiles 3 C4 2 5
