6.8-3 An IPN 240 steel beam has the cross section shown in the figure. The dimensions are b = 106 mm, h = 240 mm, tw = 8.7 mm, and t = 13.1 mm. The loads on the beam produce a shear force V = 35 kN at the cross section under consideration. (a) Use centerline dimensions to calculate the maxi- mum shear stress 7max in the web of the beam. (b) Use the more exact analysis of Section 5.10 in Chapter 5 to calculate the maximum shear stress in the web of the beam and compare it with the stress obtained in part (a).

Bending Moment

In general, we can define the bending moment as the reaction induced when a certain amount of load or force is applied to an element which makes it bend.
