Solution to example 4-1

4) Position analysis: Consider example 4-1 (page 190) of a four-bar linkage (Fig. 4-6) in the textbook. Taking the same input values as in the example (Li d-100 mm, L2-a-40 mm, L3-b- 120 mm, L4-c 80 mm), write a Matlab script for the following: a) Plot 4vs 2 using Matlab for values ranging from 0 to 360 degrees. Use at least 100 values of 2 in the range. (Remember there are two 4 values possible for every 2, each corresponding to open and crossed configuration respectively. So plot both Plot 4 values on the same plot) (20 points). b) Do the same for 3. That is, plot 3vs 2 using Matlab for at least 100 values of 2 ranging from 0 to 360 degrees. (Remember there is a different 3 for an open and crossed configuration, so plot both.) (20 points)
