What is torque testing?
Torque testing measures the rotational force required to turn or twist an object. In packaging, it is most often applied to closures such as caps, lids and twist-top mechanisms to ensure they open and close within defined performance limits.

Strain at maximum stress explained
Stress is the applied force, and strain is the resulting deformation. As a specimen is loaded, both stress and strain increase until stress reaches its peak value before the material starts to weaken.
