A spring with a stiffness of 4 × 10 ^ 2 N / m stretched 0.3 m. Find the elastic force acting on the spring.
| September 14, 2021 | education
We calculate the elastic force acting on the spring using the formula:
Fcont. = k * ∆l, where k is the stiffness of the spring (k = 400 N / m); ∆l is the amount of spring deformation (elongation, ∆l = 0.3 m).
Let’s calculate the elastic force acting on the spring:
Fcont. = k * ∆l = 400 * 0.3 = 120 N.
Answer: The spring force is 120 N.
