Biomechanics
A biomechanics researcher is studying the mechanical properties of the anterior cruciate ligament. When a constant load is applied, the ligament gradually elongates over time. When held at a constant length, the tension in the ligament progressively decreases. The loading and unloading curves on a stress-strain graph do not overlap.
