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. The channel beam is positioned on its two legs (110mm flat bars) and the 250 mm surface positioned at the top from the bottom surface, sitting on top of a machine bender on its two side 110 mm side flat bars.Find the following (hints K1 top surface corner and K2 bottom inside corner, points is on the one side of the beam: top and bottom corner):
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.
