I have no knowledge whatsoever of beams but a quick google search shows there's loads of info.

Read some of thos. your lecture notes and course texts may help too

Oooo, this is one for me...
The two main points to consider are shear stress and bending moment.
The applied load causes both of the above; therfore the beams design is critical to resist both.
A flat thin beam will resist a lower bending moment than a tall beam. The second moment of area is a value based on the cross-sectional area of the beam.
The shear stress that a beam can withstand is directly related to the cross sectional area and the material strength.
The third point to consider is the loading of the beam. A uniformly distributed load (UDL) will create different bending characteristics to a / several point loads.
So are you doing homwork, building a house or something else?
