Simplified LaCoste suspension using a zero-length spring. LaCoste discovered the zero-length spring in 1932 while performing an assignment in Arnold Romberg's undergraduate physics course. A zero-length spring is a spring supported in such a way that its exerted force is proportional to its length, rather than the distance it is compressed.
Simplified LaCoste suspension using a zero-length spring Spring length L vs force F graph of ordinary (+), zero-length (0) and negative-length (−) springs with the same minimum length L 0 and spring constant. Zero-length spring is a term for a specially designed coil spring that would exert zero force if it had zero length. That is, in a line ...
Vertical instruments use some kind of constant-force suspension, such as the LaCoste suspension. The LaCoste suspension uses a zero-length spring to provide a long period (high sensitivity). [ 22 ] [ 23 ] Some modern instruments use a "triaxial" or "Galperin" design , in which three identical motion sensors are set at the same angle to the ...
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.)

Torsion bar suspension inside Leopard 2 Schematic of a front axle highlighted to show torsion bar. A torsion bar suspension, also known as a torsion spring suspension, is any vehicle suspension that uses a torsion bar as its main weight-bearing spring. One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end ...
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.
The vertical volute spring suspension system is a type of vehicle suspension system which uses volute springs to compensate for surface irregularities. This type of the suspension system was mainly fitted on US and Italian tanks and armored fighting vehicles starting from throughout the 1930s up until after the end of the Second World War in 1945.
