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)(bh^{3}- bh_{1}^{3}+ th_{1}^{3}) = 3.43X10^{-4}m^{4}

Max Shear Stress = (Vb/8It)(bh^{2}- bh_{1}^{2}+ th_{1}^{2}) = 28.4MPa

Min Shear Stress = (V/8It)(h^{2}- h_{1}^{2}) = 21.9MPa

Avg Shear Stress = (V/th_{1}) = 27.4MPa

V_{web}= (th_{1}/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.
