Project 1
Consider the truss shown below subjected to the loads shown on the figure where Q = 1000 lbs and L = 1 ft. The outer members (indicated by thick lines) have an area of 16 in² and the inner members (indicated by thinner lines) have an area of 4 in². All members are made from steel with a modulus of elasticity E = 30 x 10^6 psi. Write a 2D truss MATLAB code and use it to analyze the structure.
Submit your code along with a short and concise report that includes the following:
1) The undeformed and deformed shapes of the structure (use a magnification factor where the difference is noticeable).
2) The largest tensile and compressive stresses in the members as well as their locations (label clearly on a separate figure).
3) The reaction forces at the supports (label clearly on a separate figure).
Note: The node and element numbering scheme are provided below. Numbers inside the parenthesis are element numbers and numbers without parenthesis are node numbers.
