What is the maximum load recorded in the extension graph results?

The maximum load recorded in the extension graph results is significant because it reflects the highest level of stress or force that a particular material or structural component can withstand before failure. By identifying this maximum load, engineers can assess the safety margins and performance characteristics of the material during testing.

In this case, the choice of 198 kN as the maximum load indicates that during the extension testing, this was the peak load measured before any noticeable deformation or failure occurred. Understanding the precise maximum load helps in determining the material's strength and allows for better predictions about how it will behave in real-world applications.

This high value suggests that the material or system being tested has a robust design and can sustain substantial forces, making it suitable for various engineering applications where load-bearing capacity is critical.
