Determine the spring elongation if it is acted upon by a force of 10 N and a spring rate of 500 N / m.

The elastic force that acts on the spring can be calculated using the formula:

Fcont. = k * ∆l, where Fcont. – acting elastic force (Fel. = 10 N), k – spring stiffness (k = 500 N / m), ∆l – spring elongation.

Let us express and calculate the elongation of the spring:

∆l = Fcont. / k = 10/500 = 0.02 m = 2 cm.

Answer: The extension of the spring is 2 cm.
