longitudinal spacing of the bolts is 200 mm. All dimensions are given in mil- limeters. Let E = 209 GPa. (a) Determine the maximum tensile, compressive, and transverse shear stresses in the beam. (b) Determine the maximum shear stress in the beam. (c) Determine the maximum average shear stress in the bolts. (d) Determine the maximum bending deflection of the beam. 12 mm dia bolts 100 kN 8 kN/m 800 400 600 800 140 90 View A-A enlarged 150 180 3.30 The steel beam shown is constructed of a channel with a center wall and a flat plate bolted to the top. The wall thickness of the channel is 15 mm. The 5. Text Problem 3.30, Parts (a), (b) & (c). (Part (d) is better solved using energy methods.) Partial answers: max- 154 MPa; Taverage,max,bolts 557 MPa (very high!).
