ESP 3-6: The simply supported beam is built up from three boards by nailing them together as shown. The wood has an allowable shear stress of Tallow=1.9 MPa, and an allowable bending stress of allow=8.4 MPa. The nails are spaced at s = 75 mm, and each has a shear strength of 1 kN. Determine the maximum allowable force P that can be applied to the beam. А. -1m- 25 mm 25 mm 200 mm 125 mm
