A simply supported steel beam of length L = 1.5 m and rectangular cross section (h = 75 mm, b = 20 mm) carries a uniform load of q = 48 kN/m that includes its own weight. The maximum transverse shear stress on the cross section at 0.25 m from the left support is approximately:

(A) 20 MPa

(B) 24 MPa
