Formel
k = F / x, where k is the spring constant (N/m), F is force (N), x is displacement (m). Energy = ½kx².
Häufig gestellte Fragen
What is Hooke's law?
Hooke's law states that the force needed to extend or compress a spring is proportional to the displacement: F = kx.
What are typical spring constant values?
Ranges from ~1 N/m for soft springs to >100,000 N/m for stiff industrial springs.
