just started looking at area moments.
question i am stuck on is below.
use the area-moments to calculate the mid span deflection produced by the given loadings, showing clearly all steps in the method and calculation:
support condition: simply supported
span: 7.20m
section: 406x140x39 kg/m UB
material: mild steel
loading: 24 kN/m UDL
believe i have to find delflection for the beam first, then i can calc the mid span deflection. WL cubed/ E I
so first need to find the stifness of the beam , can look on net to get a figure for mild steel.
i have found one at 210kN/mm squared.
so would i have 24kN x 7.20m / 210 x 406x140x39 kg/m UB
im just confused on putting all the figures togther.
if somone could help.
