An engineer is testing a synthetic polyurethane ligament designed for robotic joint reconstruction.

a.

Explain what is meant when the synthetic ligament is elastically deformed.

[1]
b.

For small extensions, the ligament behaves like a linear spring with a spring constant of 320 N/m320\text{ N/m}320 N/m. Calculate the elastic potential energy stored in the ligament when it is stretched by 7.5 cm7.5\text{ cm}7.5 cm.
