Lab: Position Velocity Acceleration (PVA) Analysis PVA Post Lab assignment (45 points) ME370 Spring 2022 The goal of this exercise is for you to understand how the PVA MATLAB program operates for more complex mechanisms. You are encouraged to make use of this code for the project. Model the linkage system below by modifying the PVA.m routine that you applied during lab for the 4-bar linkage. You will need to use the information provided in the Appendix below on slider constraints and the video on sliders on Canvas. A Whitmore quick return mechanism is shown in Fig. 1 below. It consists of 6 links (including ground), 5 rotary joints (as numbered in the picture) and 2 sliding constraints. The distance between nodes 1 and 2 is 5 meters and that they are vertically aligned. The ratio of the distances between nodes 2 and 3 to that of the distance between 3 and 4 is 3:1. Nodes 4 and 5 are initially horizontally aligned and 3 meters apart. Finally, node 4 is 5 meters away (total) from node 1 and the ground with the sliding block is 3 meters above node 1. You may assume the slider friction to be zero.
