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 = 430 mm tw = 14 mm d = 110 mm t = 9.6 mm Additionally: • The area of each pipe is A = 3028 mm2. • The moment of inertia of the entire beam cross section about the z centroidal axis is IZ = 325870000 mm4. If the beam will be subjected to a shear force of V = 225 kN, determine the shear stress at point H, located at yH = 110 mm above the z centroidal axis.

Question
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 = 430 mm
tw = 14 mm
d = 110 mm
t = 9.6 mm
Additionally:
• The area of each pipe is A = 3028 mm2.
• The moment of inertia of the entire beam cross section about the z centroidal axis is IZ = 325870000 mm4.
If the beam will be subjected to a shear force of V = 225 kN, determine the shear stress at point H, located at yH = 110 mm above the z centroidal axis.
