A simply supported beam AB has a clear span of 7 meter. The bending moment diagram (BMD) of the beam due to a single concentrated load is shown in the figure below.
The magnitude of the concentrated load in kN is _________.
-
- 12
- 7
- 21
- 42
Correct Option: C
For eccentric point load on a simply supported beam 
Moment along any plane xx’,
MX = RA x = Wbx / L
MX = Wbx / L
Maximum Bending Moment
| = | = | |||
| L | 7 |
| 36 = | ||
| 7 |
| W = | = 21 | |
| 12 |
