![The beam cross section shown below has been proposed for a short pedestrian bridge. The cross section will consist of two pipes that
are welded to a rectangular web plate. Dimensions of the cross section are:
h = 390 mm
tw = 12 mm
d = 100 mm
t = 6.4 mm
Additionally:
• The area of each pipe is A = 1882 mm².
• The moment of inertia of the entire beam cross section about the z centroidal axis is lz=171660000 mm4.
If the beam will be subjected to a shear force of V = 120 kN, determine the shear stress at point H, located at yμ = 100 mm above the z
centroidal axis.
