(ii) Create a plot of x 1 vs Y for Y from 0 to 10 (iii) Within this interval, what value of Y maximizes x 1 ? What is the maximum value of x 1 ? 2/. The diagram below illustrates a shear leg crane. What are the tensions in each of three truss members, the tension T in the guy line, and the horizontal and vertical reactions (H and V) at the base? The numbers by the truss members (1, 2, 3) identify the members. Use these numbers in outputting your results....
