Answer #1

Answer: If any object such as spring, steel, elastic band undergo streching or compression the potential energy is stored. This potential energy is called elastic potential energy. Tendons in the body having a elastic property when it stretches the elastic potential energy is stored in that.

It is calculated by the formula:

Potential energy = 1/2 ks​​​​​2​

In that k is stiffness constant and s is the displacement or the how much distance the tendon or an object is to be stretched .

k = 300 N/m s = 10 cm or 0.1m

PE = 1/2 × 300× (0.1)2

= 1/2 × 300 × 0.01

= 1/2 × 3

PE = 1.5 joules or kg m​​​​​​2​​​​​/ s​​​​​​2

The energy stored in the tendon is 1.5 joules.

Tendons are strong elastic fibers that attach muscles to bones. To a reasonable approximation, they obey Hooke's law. In laboratory tests on a particular tendon, it was found that, when a 250 g object was hung from it, the tendon stretched 1.21 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 143 N . By how much can the tendon stretch without rupturing? How...

We can derive the potential energy stored in an ideal spring when it is stretched or compressed by computing the work done due to Hooke’s law. In this experiment we will be working with springs. When they are not being stretched by some external force, the coils of these springs are held tightly together by the spring’s rigidity. They are held so tightly that a small amount of weight can be hung from these springs, and they don’t stretch at...
