The bear 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 = 14 mm d = 100 mm t = 4.8 mm Additionally: • The area of each pipe is A = 1436 mm². • The moment of inertia of the entire bear cross section about the z centroidal axis is lz=140920000 mm². If the bearn will be subjected to a shear force of V = 170 kN, determine the shear stress at point H, located at y = 100 mm above the z centroidal axis.

The bear 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 - 14 mm
d = 100 mm
t = 4.8 mm
Additionally:
• The area of each pipe is A = 1436 mm².
• The moment of inertia of the entire bear cross section about the z centroidal axis is lz=140920000 mm².
If the bearn will be subjected to a shear force of V = 170 kN, determine the shear stress at point H, located at y = 100 mm above the z
centroidal axis.
