BS tables of properties for universal beams

[Gclark]

Hi I am a HNC student an am having trouble with this question below...

A universal I section beam is simply supported at each end and must withstand concentrated shear force of 240kN vertically downwards.
if the maximum allowable shear stress in the beam is to be 65MkN/m^2 determine the suitable section for a beam using the BS tables of properties for universal beams.
ignore the mass of the beam.

work be greatly appreciated for any help

thanks :)

I have the BS tables just need the formulas. i just have some basic knowledge and am looking for some advice.

thanks.

When you say "concentrated shear force", do you mean "concentrated force? When you say "65MkN/m^2", do you mean "65 MN/m^2" or "65 kN/m^2" ? Tell us more what you can say about this problem.
