Explanation:

When a load is excessively increased in a simply supported beam, it can lead to the formation of a hinge-like point at both ends of the beam. This can be explained as follows:

1. Concept of Hinge-like Point:
A hinge-like point is a location where the beam experiences zero bending moment. It is the point where the shear force changes its sign and the bending moment changes its nature (from positive to negative or vice versa).

2. Simply Supported Beam:
A simply supported beam is a beam that is supported at its two ends and is free to rotate and have vertical movement at these points. The supports can be in the form of pins or rollers.

3. Load Increase:
When the load on a simply supported beam is increased, it creates a reaction force at the supports. This reaction force generates internal forces such as shear force and bending moment within the beam.

4. Bending Moment Distribution:
The bending moment distribution in a simply supported beam depends on the type and magnitude of the load. In a uniformly distributed load, the maximum bending moment occurs at the center of the beam and decreases towards the ends.

5. Excessive Load:
When the load on the beam is excessively increased, the bending moment at the ends of the beam can become significant. If the bending moment exceeds the capacity of the beam to resist it, a hinge-like point can form.

6. Hinge-like Point Formation:
At the hinge-like point, the bending moment becomes zero, and the shear force changes its sign. This occurs because the excessive load causes the beam to undergo significant deflection and rotation at the ends.

7. Hinge-like Point at Both Ends:
In the given problem, the question states that the hinge-like point forms when the load is excessively increased. Since the beam is simply supported at both ends, the excessive load will cause the beam to rotate and deflect at both ends. Therefore, the hinge-like point will form at both ends of the beam.

In conclusion, when the load on a simply supported beam is excessively increased, a hinge-like point forms at both ends of the beam. This occurs due to the rotation and deflection of the beam caused by the excessive bending moment at the ends.
