The beam AB can safely support internal shear forces of 30 kN ar bending moments of 58 kNm. Using this criteria, can the beam safely sustain the loads of wo = 2.4 kN/m, w₁ = 3.6 kN/m, F₁ = 7.5 kN and F₂ = 9.6 kN.

A simply supported rectangular beam of length 6.45m has a width of 437.5 and an effective depth of 692.5. The beam is to be reinforced using 12 mm bars. The beam supports service dead loads of 31 kN/m and 39.5kN/m., respectively. the fc' is 28 and fy is 420. 1. Calculate the ultimate moment capacity of the beam. 2. Calculate the height of the equivalent stress block. 3. Determine the number of bars required for this beam

An l-section beam, 150 mm deep by 80 mm wide, with web 20 mm thick and flanges 15 mm thick, is simply supported and carries a uniformly distributed load. Calculate the span length if the maximum shear stress is 0.25 times the maximum bending stress. (1. 248 m) 9,
