Late submission will not be accepted. Problem You are part of a design team for designing a new plate cam with a radial reciprocating roller follower. The input, rise and fall and the output motion is shown in the following table. The base circle has a diameter 3 in and the diameter of the roller is 1 in. Displacements are specified as follow: Lift L (in) 3 0 -3 Input angle (deg) 0°-90° 900-105° 1050-195 1950-210° 210"-270° 270-285 2850-345° 3450-360° 0 Outputy Cycloidal rise Dwell Cycloidal fall Dwell Simple harmonic rise Dwell Simple harmonic fall Dwell 2 0 -2 0 Project Objectives 1. Obtain and plot the lift curve (the displacement diagram) and the profile of the cam 2. Identify on your cam profile the locations and the value of the largest angle. Would the pressure angle cause difficulties for a practical cam-follower system? 3. Identify on your cam profile the location of discontinuities in position, velocity, and acceleration. 4. For the values given in Table above, what design changes would you suggest to improve the cam design? Reporting Submit one report per group. Include the following sections: 1. Cover Page 2. Objective Statement 3. Analysis of Problem and Results 4. Conclusions 5. Appendix with Calculations and Code used in software.
