Answer :
To determine the shear force resisted by the web of the wide-flange beam, we need to use the formula:
We don't know the thickness of the web, but we can assume that it is equal to the flange thickness since wide- flange beams are designed to have equal flange and web thicknesses. Let's say the flange thickness is = 20 mm.
Then, the area of the web is: area = 200 mm x 20 mm = 4000 mm
Now we can find the shear stress:shear stress = 30 kN /4000 mm² = 0.0075 N / mm²
Finally, we can plug in the values to the first equation:
V = (0.5)(200 mm)(20 mm)(0.0075 N / mm ) = 15 kN
Therefore, the shear force resisted by the web of the wide-flange beam is 15 kN.
