SUMMARY
The ultimate tensile stress of rubber is defined as the maximum stress that the material can withstand before failure, calculated as force divided by the cross-sectional area. In rubber, the ultimate tensile strength is not constant due to changes in cross-sectional area under tension. The point on a force-extension graph that indicates ultimate tensile stress corresponds to the maximum point before the material breaks. This distinction is crucial for understanding the mechanical properties of rubber and similar materials.
