Relationship between load and deflection

[jon1984]

Hi,

Below is a very simple answer as to what happens to a beam when it has a load applied.

"When a load is applied to a beam, delfection occours. If not much deflection, then object is stiff. Linear relationship."

How could i further explain this, or is this simple enough?

The linear relationship really only holds true for low strains.

Thank you for your question. I would say that your explanation is a good start, but it could be further elaborated upon to provide a more comprehensive understanding of the relationship between load and deflection. Here are a few points you could consider adding to your explanation:

1. The load applied to a beam causes it to bend or deform, which is known as deflection. This deflection is caused by the internal stresses and strains that are created within the beam as a result of the applied load.

2. The amount of deflection that occurs is directly proportional to the magnitude of the load applied. This means that as the load increases, so does the deflection.

3. The relationship between load and deflection is linear, meaning that the deflection increases in a constant and predictable manner as the load increases. This can be represented by a straight line on a graph.

4. The stiffness of a beam refers to its ability to resist deflection when a load is applied. A stiffer beam will experience less deflection for a given load, while a more flexible beam will experience greater deflection for the same load.

5. The material and dimensions of a beam also play a role in the relationship between load and deflection. A stronger and thicker beam will be able to withstand larger loads and experience less deflection, while a weaker and thinner beam will deflect more under the same load.

I hope this helps to further clarify the relationship between load and deflection for you. Let me know if you have any other questions.
