A cantilever beam experiences a point load at its free end (Point A). The member has a length of L and a rectangular cross section of base b by height h. L. b. where P- 5 kN, L 3 m, b 6 cm, and h= 20 cm How much would be the axial shear stress in kPa as found by r ? (You must provide an answer before moving to the next part.) The axial shear stress would be kPa.
