What's the importance of a spring force constant of 1634N/m?

AI Thread Summary
The discussion centers on the spring force constant of 1634 N/m and its relevance in practical applications. Users suggest searching for the modulus of elasticity for related information, noting that the spring constant varies significantly based on the object's shape and displacement. Recommendations include checking McMaster-Carr for spring specifications and considering experimental methods to determine spring constants. The conversation also touches on the conversion between Newtons and pounds for better understanding. Overall, the importance of understanding spring constants is highlighted in relation to their practical uses, such as in pogo sticks.

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:
