    - Bending moment diagram for simply supported beam is as shown above. The formula used to calculate bending moment at central point load is given as:

    M = W/2 x (L/2) = WL/4

    Given: Load (W) = 600 N, Length of beam (L) = 20 m

    Formula: Bending moment (M) = WL/4

    Solution:

    Substituting the given values, we get

    Bending moment (M) = WL/4

    = (600 x 20) / 4

    = 3000 Nm

    Bending moment (M) for simply supported beam is 3000 Nm.
