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

Click For Summary

Discussion Overview

The discussion revolves around the significance of a spring force constant of 1634 N/m, including inquiries about the range of spring constants for various items and methods to determine or find these values. Participants explore both theoretical and practical aspects of spring constants.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Homework-related

Main Points Raised

  • Some participants express difficulty in finding resources that list spring force constants for various items.
  • One participant suggests searching for "modulus of elasticity" but notes its applicability is limited to small displacements, highlighting the importance of an object's shape for larger displacements.
  • A participant mentions an article that describes a method to experimentally determine a spring constant.
  • Another participant recommends checking suppliers like McMaster-Carr for spring constants, indicating that they provide ratings in lbs/in and suggesting a conversion to Newtons.
  • One participant calculates that a spring constant of 1634 N/m would compress by 1 meter under a 163 kg mass, speculating it might relate to the spring on a pogo stick.
  • There is a correction regarding the initial mention of 1634 N/m to 163.427 N/m, indicating a potential misunderstanding or typo in the values discussed.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the importance of the specific spring constant or the best resources for finding spring constants, indicating multiple competing views and unresolved questions.

Contextual Notes

Some limitations include the dependence on definitions of spring constants, the context of application (e.g., small vs. large displacements), and the potential confusion regarding the values mentioned in the discussion.

Who May Find This Useful

This discussion may be useful for individuals interested in mechanical engineering, physics, or those looking to understand spring constants in practical applications.

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:
