Question

Two leopards are fighting over a piece of meat they caught while hunting. The leopards pull on the meat muscle with a force of 100. N, stretching the 0.10-m-long tendon by 0.0080 m. If the cross-sectional area of the tendon is 1.0 105 m2, what is its stretch modulus?

Answer 1

Stretch Modulus of the given is

`Modulus = 1.25 * 10^8 N/m^2`

Step-by-step explanation:

By the law of elasticity we know that the ratio of stress and strain is known as modulus of elasticity

So here we have

`Modulus = (stress)/(strain)`

here we have

`stress = (Force)/(Area)`

`stress = (100)/(1.0 * 10^(-5))`

`stress = 10^7 m^2`

now similarly we have

`strain = (\Delta L)/(L)`

`strain = (0.0080)/(0.10)`

`strain = 0.08`

Now we have

`Modulus = (10^7)/(0.08)`

`Modulus = 1.25 * 10^8 N/m^2`
