How to determine length of a spring

AI Thread Summary
To determine the length of a spring without visual information, one can use the spring rate and the change in object position from uncoiled to fully coiled states. Hooke's Law may not yield accurate results if the system is dampened, as it primarily applies to ideal springs. The resistance rates of compression and rebound can also affect calculations, complicating the determination of spring length. It may be necessary to consider additional factors such as the damping characteristics and the specific application context. Accurate measurements or further data may be required for a reliable calculation.

Hi Everyone,

Kind of a tough question here. How do I determine the length of a spring if we don't have any visual information about it? All we have is the spring rate & change of object position from when the spring is uncoiled, to fully coiled.

Anyone have any ideas on this? I tried the hooke's law formula but it gave me some goofy length equations which wouldn't make sense.

Also, the system is dampened and we have the resistance rates of the compression and rebound resistance.

Thread 'Is 'Velocity of Transport' a Recognized Term in English Mechanics Literature?'

Here are two fragments from Banach's monograph in Mechanics I have never seen the term <<velocity of transport>> in English texts. Actually I have never seen this term being named somehow in English. This term has a name in Russian books. I looked through the original Banach's text in Polish and there is a Polish name for this term. It is a little bit surprising that the Polish name differs from the Russian one and also differs from this English translation. My question is: Is there...

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
