Hooke’s Law

Hooke’s Law                                   $F = -k \Delta x$ States that within the limit of proportionality, the extension produced in a material is directly proportional to the load applied SI unit of k: Nm-1 $\uparrow$ k( Higher stiffness), $\downarrow$ extension Applies to springs, elastic springs and metals in form of wires Springs connected in parallel $k_{eff} \, = \, k_{1} + …
