Solution: Tendons are strong elastic fibers that attach muscles to bones. To a reasonable approximation, they obey Hookes law. In laboratory tests on a particular tendon, it was found that, when a 251 g object was hung from it, the tendon stretched 1.23 cm .Find the force constant of this tendon in N/m.Because of its thickness, the maximum tension this tendon can support without rupturing is 141 N . By how much can the tendon stretch without rupturing?How much energy is stored in it at that point?

Problem

Tendons are strong elastic fibers that attach muscles to bones. To a reasonable approximation, they obey Hookes law. In laboratory tests on a particular tendon, it was found that, when a 251 g object was hung from it, the tendon stretched 1.23 cm .

Find the force constant of this tendon in N/m.

Because of its thickness, the maximum tension this tendon can support without rupturing is 141 N . By how much can the tendon stretch without rupturing?

How much energy is stored in it at that point?
