  1. 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 _________.
    1. 12
    2. 7
    3. 21
    4. 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

=
Wab
=
(W × 3 × 4)
L7

36 =
12W
7

W =
(36 × 7)
= 21
12
