Homework Statement
Okay this is the problem I have:
I have a Steel Channel beam which has an cross sectional height of 300mm. It is 150mm in depth. Its wall thickness is 20mm.
This beam is 6meters long as has a 10kN/m UDL applied. It is fixed at one side and unsupported at the tip.
I have worked out the Neutral Axis about the xx at 44.8214mm and the Moment of Inertia as 32.93x109mm4
I now need to determine maximum tensile bending stress and its exact location in the beam cross section.
Homework Equations
I know maximum bending stress is equal to (max stress = my/I)
The Attempt at a Solution
Now I know I, and I have YCenter at 150mm and xCenter at 44.8214mm now I don't know how to get Mmax and it's exact distance.
I think Mmax is (L2x10kn/m)/2 but I could be incorrect?
I have attached a picture of my working if that helps
