Calculate the force required to stretch an elastic material by 13m. Find the stiffness of the material is 10NM^-1

3 answers

We can use Hooke's Law to solve this problem:

F = kx

where F is the force required, k is the stiffness of the material, and x is the distance stretched.

Substituting the given values:

F = (10 N/m) * (13 m)
F = 130 N

Therefore, the force required to stretch the elastic material by 13m is 130N.
A force of 0.8N stretches on elastic spring by 20cm. Find the elastic constant of the spring
We can use Hooke's Law to solve this problem:

F = kx

where F is the force applied, k is the stiffness or elastic constant of the spring, and x is the displacement or stretch produced.

In this case, the force applied is 0.8N and the displacement produced is 20cm, or 0.2m. Substituting these values:

0.8N = k * 0.2m

Solving for k:

k = 0.8N / 0.2m

k = 4 N/m

Therefore, the elastic constant of the spring is 4 N/m.
