## Homework Statement

Determine the Max, Min & average shear stress, and the shear force in web

V = 125kN

Note th attachment

## Homework Equations

## 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.
