Correct Option: A
A single span simply supported reinforced concrete beam (250 mm wide and 480 mm effective depth) is subjected to a concentrated load of 120 kN at its mid-span. Neglecting self-weight of the beam, the nominal shear stress (MPa) at the support section is
| Reaction at the end = | = 60kN | |
| 2 |
| Shear stress = | = | × .48 m = 0.5 MPa | ||
| area | 0.25 m |
(1 MPa = 106Pa =106N/M2)
