In the simplification of the loading system the net force acts at the centroid of the loading body. That is if the loading system is in the form of the triangle then the at the distance 2 by 3 of the base the net force of the loading will act. And the load will be half the area of the loading.

The correct answer is option 'A', which states that the net force acts at the centroid of the loading body. In order to understand why this is the case, let's break down the concept of the centroid and its relation to the net force acting on a body.
- Centroid: The centroid of a body is the geometric center or average position of all the points in the body. It is a point that represents the overall distribution of mass in the body. In other words, it is the balance point of the body.
- Net force: The net force acting on a body is the vector sum of all the individual forces acting on the body. It represents the overall force experienced by the body.
- Simplification of the loading system: When simplifying a loading system, we aim to represent the system with a single force that has the same effect on the body as the original loading system. This single force is called the net force.
Now, let's see why the net force acts at the centroid of the loading body:
1. Definition of centroid: As mentioned earlier, the centroid represents the overall distribution of mass in the body. It is the balance point of the body, where the body can be considered to be in equilibrium.
2. Equilibrium condition: When a body is in equilibrium, the net force acting on it is zero. This means that the vector sum of all the forces acting on the body is zero.
3. Simplified loading system: In order to simplify the loading system, we need to represent the original loading system with a single force that has the same effect on the body. This single force is the net force.
4. Balance of forces: Since the net force is zero in equilibrium, it means that the single force representing the simplified loading system should act in such a way that it balances out all the other forces acting on the body.
5. Distribution of forces: The forces acting on a body can be distributed unevenly throughout the body. However, the centroid represents the average position of all the points in the body, taking into account the distribution of mass.
6. Balance at the centroid: By placing the net force at the centroid, it ensures that the force is distributed in such a way that it balances out all the other forces acting on the body. This is because the centroid represents the average position of all the points and takes into account the distribution of mass.
Therefore, the net force acts at the centroid of the loading body in order to simplify the loading system and ensure that the body is in equilibrium.
