Q. 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
Ans: 21
Solution:
Moment along any plane xx’,
MX = RA x = Wbx / L
MX = Wbx / L
Maximum Bending Moment
