Question
Determine the maximum compressive bending stress (o max.comp.x=2.8) for the beam section at
distance 2.8 m from A, for the beam loaded in Figure 5.1la1(b), in N/mm2. The cross section of the beam
is shown in Figure 5.1a1(a).
Given D = 120 mm, t = 15 mm, location of centroid of the cross section = 62.1 mm from x-axis, second
moment of area with respect to its centroidal x-axis (Iy) = 7.08 x 106 mm“, a = 0.9 m, b = 0.9 m, and P1 =
20 kN.
