How to Demonstrate Hooke's Law with a Spring and Weights

[ramat]

hi, i am just having some problems with understanding the hook's law lab, if anyone has a "hook's law" can you please post it or you can email it to me. here is my address. dino_679@hotmail.com Thanks i will really appreciate it.

This belongs in homework help. Will someone move it ?

ramat,

Hooke's Law just says the force produced by a spring is proportional to the distance it is stretched or compressed. If you double the amount of stretch, for example, you double the amount of force it produces.

Hook's law

I'm having problems looking for a good example on how to demonstrate hook's law, i'll be more than thankful if someone can help me with that

One way: hang the spring vertically, put a weight on it and measure the extension. Put twice the weight on it and measure the weight again.

Another way: put the spring horizontally, attach a scale to it (one of those that you hang a weight to) and pull. The scale will show the force and you can measure the extension.

Hooke's law is part of what we commonly call "experimental phyics".Mathematical formulatios of the physical laws are proven by experimental methods only.In the case of the Hooke law,just take a spring and various masses and place them in the gravitational field by hanging one end of the string on a support and at the other end put the weights.Take a ruler and measure if the strings's length doubles as u put 2 different weights one 2 times heavier than the other.If it's so,u have just proven Robert Hooke's law.
Force (magnitude) measuring apparatus called "dynamometers" function according to Hooke's law.

PS.I hope u weren't asking about the generalized Hooke's law (which has nothing to do actually with Robert Hooke)...Those are messy tensors...

EDIT:U have more versions of basically the same thing.The important thing is that u got the right picture.
