It depends on what variables are plotted.
The straight line graphed (according to the variables) could be the value "k" which is the spring constant. I remember doing an experiement in a labaratory class and we put weights on the spring and measured the distance that the spring extended. From this we were able to graph weight vs. meters and this would give us a straight line... this line would be "k" and would prove Hooke's Law.
Hookes law
A spring scale is simply a spring fixed at one end with a hook to attach an object at the other. It works on the principle of Hookes Law, that states that the force needed to extend the spring is proportional to the distance that the spring extended from it's fixed position.
Not sure what a sprial spring is but a spiral sprig is one whose radius increases from one end to the other.
Wind/air currents which make spring to oscillate. Measuring extension when spring is oscillating/has not yet stabilized. Including the length of the hooks to the extension of the helical coils of spring.
You could use two or more spiral springs to share the weight. You could use a pulley system with a big mechanical advantage and use the spiral spring to measure the reduced load. Or you could use a lever with a big mechanical advantage in a similar way.
Hookes law
"Spiral" can be a noun as in, "The spring is in the shape of a spiral", or it can be a verb as in, "He would eventually spiral out of control."
You can tell if a spiral spring pitch is normal by this equation; 0.2*D < p < 0.4*D. However, you can calculate a spiral spring pitch by l = πDn, A = πd2 /4.
Its all to do with Hookes law................
How do calculate spiral length of Spiral rings
Hooke's law of elasticity is an approximation that states that the extension of a spring is in direct proportion with the load applied to it.
A spring scale is simply a spring fixed at one end with a hook to attach an object at the other. It works on the principle of Hookes Law, that states that the force needed to extend the spring is proportional to the distance that the spring extended from it's fixed position.
Hooke's law was designed to determine the restoring force of a spring, given its spring constant and the displacement of the spring from its equilibrium position. The law is written as follows: F = -kx; in which "F" is the restoring force, "k" is the spring constant, and "x" is the spring's displacement.
No, by definition Hooke's law relates to linear elastic only; when outside the elastic region it does not apply.
You need a spring scale machine, as commonly found in the aircraft industry.
Rigidity = spiralness + spinginess
