A box beam is constructed from four boards nailed together and is loaded by distributed and point forces as shown in Figure 2. Each nail is made of A-36 steel material and has a diameter of 6mm. Each nail can support a shear stress of tallow= 80 MPa. By drawing the shear diagram for the beam, a. Determine the critical section for shear where the resultant shear force is max. b. Determine the maximum spacing s of the nails for the first and second cross-sections. 50 mm +100 mm-H 50 mm 50 12 kN mm. 8 kN/m A 50 mm 4 m -2 m EHuu 001 H
