Step 1
D. The maximum stress
Answer
In the context of the stress-strain graph shown in Figure 1.12, point D typically represents the maximum stress that the material can withstand before failure. This is known as the ultimate tensile strength, where the material has reached its peak load-bearing capacity. Beyond this point, the material experiences necking and eventual failure.
