Hi I'm new here and I've checked everywhere on google but I can't seem to find a website that'll tell me the spring force constant of items. Also what things would be in the range of a spring force constant of 163.427 N/m/

You may have better luck if you search for "modulus of elasticity". However, that only applies to small displacements. For larger displacements, the shape of the object is critically important - coil springs are shaped to produce a particular spring constant, for example, and it's very different from the spring constant of a solid block of the same steel that spring is made of.

I think your best chance of finding such a list would be if you were actually shopping for springs.
McMaster-Carr sells springs, selectable by "spring force constants".

As you can see, they rate them by lbs./in., so you'll have to do the conversion.

Their extension springs range from 0.004 lbs/in to 203 lbs/in, so I'm guessing you'll find what you're looking for.

1634N/m... So a 163kg mass compresses it 1 meter. 81.5 about half a meter. Perhaps in the ball park of the spring on a pogo stick?

What was the question?

he changed that to 163.427 N/m in his first post :wink:
