A channel beam was tested in a bending machine and it was noted that internal bending moment about the centroidal z axis (half of 250 length = 125) was 7.40kN.m. Find the following (hints K1 and K2 points is the hieght of the beam, with the two points on either end of beam on the one side):
find the maximum tensile stress due to bending in the beam.
find the maximum compressive stress due to bending in the beam.
A cross-sectional of a channel beam and its dimensions
length = 250 mm
hieght = 110 mm
Thickness = 15 mm all round.
