1. The problem statement, all variables and given/known data Determine the Max, Min & average shear stress, and the shear force in web V = 125kN Note th attachment 2. Relevant equations 3. The attempt at a solution First I calculated the Moment of Inertia I = (1/12)(bh3 - bh13 + th13) = 3.43X10-4 m4 Max Shear Stress = (Vb/8It)(bh2 - bh12 + th12) = 28.4MPa Min Shear Stress = (V/8It)(h2 - h12) = 21.9MPa Avg Shear Stress = (V/th1) = 27.4MPa Vweb = (th1/3)(2[tex]\tau[/tex]max + [tex]\tau[/tex]min) = 119.6 kN Did I use all the correct equation. The example uses these equations but says they are in the web.
