Question

In a simply supported beam with a uniform load, the shear force is maximum at:

• A. The midpoint of the beam
• B. The support
• C. The center of the span
• D. At the end of the beam

Hint:

In a simply supported beam with a uniform load, the shear force is maximum at the supports and decreases towards the midpoint of the beam.

Answer 1

The Correct Option is B

Step 1: Understanding shear force distribution
In a simply supported beam with a uniform load, the shear force is the force exerted internally to resist the external load. The distribution of shear force is not uniform and varies along the length of the beam.
Step 2: Maximum shear force location
For a simply supported beam with a uniform load, the shear force is maximum at the supports (where the beam is supported). At the support, the shear force is at its highest because the external load is directly transmitted to the supports.
Step 3: Shear force at other locations
The shear force decreases as we move from the support towards the midpoint of the beam. At the midpoint, the shear force is zero, and beyond the midpoint, it begins to increase in the opposite direction.
