Question 2 A simply supported beam of a channel section (see Figure Q2) is loaded by a vertical point load P= 10 kN (acting upwards) at mid-span. The length of the beam is L=3 m, the overall width and height of the section are of the same value a 50 mm, and the thickness of all three parts of the section is t= 10 mm. Find the value and location of the maximum shear stress in the beam. Figure Q2

L For the beam shown above with length L = 7 m with the applied uniformly distributed load of w = 14 KN/m, what is the maximum bending stress if the beam has a cross section with the following dimensions: b = 100 mm d = 250 mm t = 20 mm tw = 15 mm tw
