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

Answer:

Stretch Modulus of the given is

$Modulus = 1.25 \times 10^8 N/m^2$

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

$Modulus = \frac{stress}{strain}$

here we have

$stress = \frac{Force}{Area}$

$stress = \frac{100}{1.0 \times 10^{-5}}$

$stress = 10^7 m^2$

now similarly we have

$strain = \frac{\Delta L}{L}$

$strain = \frac{0.0080}{0.10}$

$strain = 0.08$

Now we have

$Modulus = \frac{10^7}{0.08}$

$Modulus = 1.25 \times 10^8 N/m^2$
