Question:
figure 1
figure 2
A column with a wide-flange section has a flange width
b
=175mm, height
h
=175mm, web
thickness
tw
=7.5mm, and flange thickness
tf
=11mm(Figure 1). Calculate the stresses at a
point50mmabove the neutral axis if the section supports a tensile normal force
N
=2kNat
the centroid, shear force
V
=6kN, and bending moment
M
=4.4kN⋅mas shown(Figure 2).
Part A -Normal stress
Calculate the normal stress at the point due to the internal normal force on the section.
Express your answer with appropriate units to three significant figures.
Part B -Shear stress
Calculate the magnitude of the shear stress at the point due to the internal shear on the
section.
Express your answer with appropriate units to three significant figures
Part C -Combined normal stress
Calculate the combined normal stress at the point due to internal normal force and the
internal bending moment on the section.
Express your answer with appropriate units to three significant figures.
