Hi guys,

I urgently need help with one of my engineering question tutorials! No-one I ask seems to know the answer!

A mild structural steel beam has a solid square cross section of 100mm and is simply supported by two supports 3m apart. Calculate the dead load that can be safely supported when applied to the middle of the beam.

I need to answer this question in terms using the following equations:
bending stress = M/Z
Z= I/y
M=WL/4

Any help will be much appreciated!!

Thanks guys!

P is the load applied
Z=.1^3/6
M capacity = Z*fy (*ø safety factor if required), take fy as 300mpa

Sub into m =3P/4
