Problem 1 (MATLAB allowed) Consider the balcony truss in the figure with dimensions. Using the MATLAB codes discussed in class, compute the reaction forces at the supports the deflection of each joint under the loading the average stresses in each member a. b. c. All members are made from Douglas-fir wood with a modulus of elasticity of E = 1.90x10"(lb/ in*) and cross-sectional area of 8(in2). Attach any modified code to the submitted work. 500 lb 500 lb 3 ft 3 ft 3 ft Problem 2 Review of solid mechanics (MATLAB is allowed) Determine all three the principal stresses and principal directions of the infinitesimal element as shown on the right. The numbers shown on the figure represent the magnitudes of strain components. You may use MATLAB Problem 1 (MATLAB allowed) Consider the balcony truss in the figure with dimensions.
