A load of P = 50 kN acting at an angle of ß = 32° is supported by the structure shown. The overall dimensions of the structure are a = 2 2.9 m, b = 0.3 m, c = 1.0 m, e = 0.31 m, and x₁ = 2.0 m. The cross- sectional dimensions of member BC are bf = 170 mm, tf = 13 mm, d = 330 mm, tw = 11 mm, and h = 110 mm. Determine the principal stresses and the maximum shear stress acting at point H in member BC. Show these stresses on an appropriate sketch. E 45° XI (1) B e H a X d H X
