Only Question 7-18

7-18. If the wide-flange beam is subjected to a shear of V = 30 kN, determine the maximum
shear stress in the beam. Set w = 200 mm. The neutral axis is located at y = 0.1747 m from the
bottom and INA = 0.2182(10-³) m².
7-19. If the wide-flange beam is subjected to a shear of V = 30 kN, determine the shear force
resisted by the web of the beam. Set w = 200 mm. The neutral axis is located at y = 0.1747m
from the bottom and INA = 0.2182(10-³) m¹.
