  2. Hooke's law - Wikipedia

    en.wikipedia.org/wiki/Hooke's_law

    In physics, Hooke's law is an empirical law which states that the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distance—that is, F s = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness), and x is small compared to the total possible deformation of the spring.

  3. Spring (device) - Wikipedia

    en.wikipedia.org/wiki/Spring_(device)

    A spring that obeys Hooke's Law with spring constant k will have a total system energy E of: [14] E = ( 1 2 ) k A 2 {\displaystyle E=\left({\frac {1}{2}}\right)kA^{2}} Here, A is the amplitude of the wave-like motion that is produced by the oscillating behavior of the spring.

  4. Series and parallel springs - Wikipedia

    en.wikipedia.org/wiki/Series_and_parallel_springs

    The following table gives formula for the spring that is equivalent to a system of two springs, in series or in parallel, whose spring constants are and . [1] The compliance c {\displaystyle c} of a spring is the reciprocal 1 / k {\displaystyle 1/k} of its spring constant.)

  5. Compressibility - Wikipedia

    en.wikipedia.org/wiki/Compressibility

    In transition regions, where this pressure dependent dissociation is incomplete, both beta (the volume/pressure differential ratio) and the differential, constant pressure heat capacity greatly increases. For moderate pressures, above 10,000 K the gas further dissociates into free electrons and ions.

  6. Bulk modulus - Wikipedia

    en.wikipedia.org/wiki/Bulk_modulus

    Approximate bulk modulus (K) for other substances β-Carbon nitride: 427 ± 15 GPa [7] (predicted) Water: 2.2 GPa (0.32 Mpsi) (value increases at higher pressures) Methanol 823 MPa (at 20 °C and 1 Atm) Solid helium: 50 MPa (approximate) Air 142 kPa (adiabatic bulk modulus [or isentropic bulk modulus]) Air 101 kPa (isothermal bulk modulus)

  7. Wave equation - Wikipedia

    en.wikipedia.org/wiki/Wave_equation

    A uniform bar, i.e. of constant cross-section, made from a linear elastic material has a stiffness K given by =, where A is the cross-sectional area, and E is the Young's modulus of the material. The wave equation becomes ∂ 2 u ( x , t ) ∂ t 2 = E A L M ∂ 2 u ( x , t ) ∂ x 2 . {\displaystyle {\frac {\partial ^{2}u(x,t)}{\partial t^{2 ...
