The moment diagram is when the cantilever beam whose free ends are applied with bending moment.

Acubic parabola

Bparabola

Ctriangle

Drectangle

Answer:

D. rectangle

Read Explanation:

When a moment is applied at the free end of a cantilever beam, it will be transferred to the fixed end with constant magnitude. Hence, the Bending Moment Diagram (BMD) is a rectangle as the bending moment is constant throughout the beam. This is an example of pure bending where the shear force is zero throughout the beam. The fixed end moment is equal to the applied moment.

    The shear force obtained at the midpoint of the cantilever beam is 12 kN. What is the value of uniformly distributed load w (kN/m) acting over the entire length, if the span length of the beam is 4 m?
    When the shear force at a section of a beam under bending is zero, the bending moment at that section is either a maximum or a minimum. This is because the shear force is a measure of the rate of change of the bending moment. When the shear force is zero, the bending moment is either at its peak or at its trough.
