The spring with a stiffness of 3 kN / m was compressed by 10 mm. What is the energy of a compressed spring?
| May 28, 2021 | education
k = 3 kn / m = 3000 N / m – coefficient of spring stiffness;
x = 10 millimeters = 0.1 meter is the distance the spring has compressed.
It is required to determine W (Joule) – the energy of the compressed spring.
W = k * x ^ 2/2 = 3000 * 0.1 ^ 2/2 = 3000 * 0.01/2 = 30/2 = 15 Joules.
Answer: The energy of a compressed spring is 15 Joules.
