# Shear stress in a beam

 P: 16 1. The problem statement, all variables and given/known data A simply supported beam with its cross-section is shown in the attached figure 2.2. For the beam and loading shown, determine the largest shearing stress in the section n~n and shearing stress at point a shown in cross-section of the beam. 2. Relevant equations 3. The attempt at a solution So to find the shearing stress at n-n I developed a shear diagram. Is it correct that the shear stress at n-n would be the area under this diagram from point A to n-n? That being 110kN x 0.3m which gives 33kPa? I am stuck on how to calculate the shearing stress at the point shown in the cross section. Any help would be greatly appreciated.
