How this was calculated
Hooke's Law: F = k * x, where F is force, k is the spring constant (rate), and x is displacement (deflection) from equilibrium.
Potential Energy: PE = 0.5 * k * x², the elastic potential energy stored in the spring.
Assumptions: Linear elastic spring within its proportional limit. Does not account for spring surge, fatigue, or non-linear behavior.

Hooke's Law (F = kx) describes the linear relationship between force and displacement for an ideal elastic spring. The spring rate (k) is a material and geometry property measured in force per unit length. This relationship holds for compression springs, extension springs, and torsion springs within their elastic limit.
Common applications include suspension systems, valve springs, mechanical seals, and vibration isolation. The elastic potential energy stored (PE = 0.5kx²) is critical for energy storage devices and impact absorption systems.
