A steel beam is built up from a W = 410 × 85 wide flange beam and two 180 mm × 9 mm cover plates (see figure). The allowable load in shear on each bolt is 9.8 kN. What is the required bolt spacing s in the longitudinal direction if the shear force V = 110 kN (Note: Obtain the dimensions and moment of inertia of the W shape from Table E-1(b).
