Determine the normal tensile stress and shear stress due to the load (P) and the distribute force (w) acting on the simple beam AB (Figure 3). Data are as follows: P= 6 kN, w 10 kN/m, L= 3.2 m, a= 1.7 m, d= 1.25 m, b= 80 mm, t= 25 mm, h= 120 mm, and h1 = 90 mm. Point (4-4) is in the same position of the neutral axis.
