# Determine the coefficient of stiffness of the dynamometer spring if it stretched by 10 cm under the action of a force of 4 H

October 6, 2021 | education

| Given:

F = 4 Newtons – the force under the action of which the dynamometer spring was stretched;

dx = 10 centimeters = 0.1 meters – the amount of tension of the dynamometer spring.

It is required to determine k (Newton / meter) – the coefficient of stiffness of the dynamometer spring.

To find the coefficient of spring stiffness, you need to use the following formula:

F = k * dx, hence:

k = F / dx = 4 / 0.1 = 40 Newton / meter.

Answer: the coefficient of stiffness of the dynamometer spring is 40 N / m.
