For the beam with cross-section shown, the allowable flexural stresses for tension and compression are 80 MPa and 120 MPa, respectively. Using a = 15 mm, determine a. The maximum flexural stresses in tension and compression. (10 pts.) b. The stress at a point 6 m to the right of A and 30 mm below the top. (10 pts.) c. If the 16 kN/m and 12 kN/m be replaced by a uniform load 1.5w and w, respectively and all concentrated loads and moment are removed, determine the maximum safe value of w. (10 pts.) 15 kN 8a 16 kN/m a 12 kN/m a 10a A 30 kNm 3m 7m 3 m За
