ANS : 140 MPa, 2.89 m from left

Total load w*L/2 = 50,000

Load at distance x (w*x)/L

I know that distance of maximum load = L/sqrt3 = 2.89

So the maximum bending moment = (20,000*2.89)/5 = 11560

I have out this into the formula M*Y/I =σ but get an incorrect answer

Unfortunately the picture with dimensions is unable to upload but it is an I beam with a second moment of area as 0.00003813 and a distance from the neutral axis as 0.1

Thanks
