Please answer the mechanical engineering question with a complete solution as soon as possible. Thank you

For the beam with cross-section shown, the allowable flexural stresses for tension and compression are 40 MPa and 60 MPa,
respectively. Using a = 350 mm, b = 45 mm, c = 250 mm, L1 = 3 m, L2 = 7 m, L3 = 4 m, w1 = 38 kN/m, w2 = 18 kN/m, P = 19 kN and M
= 24 kNm, determine
a. The maximum flexural stresses in tension and compression. I
b. The stress at a point 3 m to the left of the right support and 90 mm above the bottom.
c. If w1 = 1.5wɔ and all concentrated load and moment are removed, determine the maximum safe value of w1 and w2. I
