Explanation:


Introduction:
When a beam is loaded, it tends to bend. The stiffness of the beam is a measure of its resistance to bending. If the ratio of the span to the overall depth of the beam does not exceed 7, the stiffness of the beam will ordinarily be satisfactory.

Types of Beams:
There are three types of beams, i.e., simply supported beam, continuous beam, and cantilever beam. The stiffness of each beam type depends on its geometry and boundary conditions.

Simply Supported Beam:
A simply supported beam is a beam that is supported at both ends and is free to rotate at each support. The stiffness of a simply supported beam depends on its span and overall depth. If the ratio of the span to the overall depth does not exceed 7, the stiffness of the beam will ordinarily be satisfactory.

Continuous Beam:
A continuous beam is a beam that is supported by three or more supports. The stiffness of a continuous beam depends on its span, overall depth, and the distance between supports. If the ratio of the span to the overall depth does not exceed 7 and the distance between supports is not too large, the stiffness of the beam will ordinarily be satisfactory.

Cantilever Beam:
A cantilever beam is a beam that is supported at one end and is free to rotate at the other end. The stiffness of a cantilever beam depends on its length, overall depth, and the distance between supports. If the ratio of the length to the overall depth does not exceed 7 and the distance between supports is not too large, the stiffness of the beam will ordinarily be satisfactory.

Conclusion:
In conclusion, the stiffness of a beam depends on its geometry and boundary conditions. If the ratio of the span to the overall depth does not exceed 7, the stiffness of the beam will ordinarily be satisfactory in case of a cantilever beam.
