Consider a beam that is simply supported at both ends by fixed supports and a point load is applied directly in the middle. The force (F), length of beam (L), Young's Modulus (E) and tensile and crushing strength (σ). The amount of deflection is not known.
Let's say 1,000,000kN was applied to the beam, how would I calculate how large the cross-section would need to be in order for it to not fail and break?
