Extracted text: F M h B b For the given system; a) Draw bending moment and shear force diagrams. b) Determine the most critical section. c) Show the stress distribution on this critical section. d) If allowable stresses for tension and compression are 7000 N/cm² and 12000 N/em², respectively, determine the safety of the structure. GIVEN: €1 = 80 cm, €2= 40 cm, qo = 60 N/cm F= 500 N, b = 5 cm, h = 4 cm, t = 0.5 cm
