For the beam with cross-section shown, the allowable flexural stresses for tension and compression are 40 MPa and 60- MPa, respectively. Using a = 450mm, b=600mm, c=250mm, L1=2m, L2 = 8m, L3 = 4m, w1 = 32kn/m, w2 = 18kn/m, P = 19kN and M = 21kNm, determine a. The maximum flexural stresses in tension and compression b. The stress at a point 3m to the left of the right support and 90mm above the bottom c. If wi = 1.5 w2 and all concentrated load and moment are removed, determine the maximum safe value of wi and w2. P a W1 W2 b M L1 L2 L3 Note: Show all the free body diagrams in each solution.
