Question

What is the shape of the ILD for bending moment at point 'C' of a cantilever beam when the unit load is between C and B as shown in figure?

• A.
• B.
• C.
• D.

Hint:

For influence lines, understand the distribution of internal forces across the span and visualize the shape of the diagram for different loads.

Answer 1

The Correct Option is B

When the unit load is applied between points C and B of a cantilever beam, the ILD (Influence Line Diagram) for the bending moment at point C is a trapezoidal shape. Hence, the correct answer is the trapezoidal shape.
