Simple harmonic motion of coil spring

Click For Summary

Discussion Overview

The discussion revolves around the problem of determining the spring constant of a coil spring based on its stretch when a weight is applied. Participants also explore a related scenario involving the effects of cutting the spring in half on its behavior under load. The scope includes conceptual understanding and mathematical reasoning related to simple harmonic motion and spring mechanics.

Discussion Character

  • Homework-related
  • Conceptual clarification
  • Mathematical reasoning

Main Points Raised

  • One participant seeks help in calculating the spring constant for a 100 coil spring that stretches by 0.160m, questioning whether the force is simply 100.
  • Another participant points out that the problem lacks sufficient information, specifically the weight of the object, to determine the force acting on the spring.
  • A different participant introduces a scenario where a 100 coil spring stretches by 0.100m when an unknown mass is attached, and questions how the stretch would change if the spring is cut in half, suggesting a need for literature to support this concept.
  • A moderator reminds participants to avoid multiple threads on the same topic and emphasizes the importance of making an effort to solve problems independently.

Areas of Agreement / Disagreement

Participants generally agree that additional information is needed to solve the initial problem regarding the spring constant. There are competing views on the implications of cutting the spring in half, with no consensus reached on the outcome of that scenario.

Contextual Notes

The discussion highlights limitations in the provided information, such as the absence of the object's weight and the need for clarity on the spring's behavior when altered.

Who May Find This Useful

Students studying mechanics, particularly those interested in spring dynamics and simple harmonic motion, may find this discussion relevant.

hi i ned a little help with this problem please.

An object is connectedto a 100 coil spring, that is hanging from the ceiling. The spring stretches by 0,160m.
What is the spring constant?

Im not sure how to go about with this...is the force 100?

please help. Thanks

Not enough info - they don't give you the force unless they give you the weight of the object...

hi... My lecturer says that there is a concept in the following, however icannot come across any literature to substantiate it.

If you have a 100 coil spring,and an object of unknown mass is attached to the bottom of it, it will stretch by 0.100m.

If the spring is then cut into half, i,e you will now have two springs of 50 coils each, nad the same object is attached to the bottom of both the springs. By how much will each spring now stretch?

thank you
 
Please don't start multiple threads on the same topic. Threads merged. Also, we have a homework secton.

Also, we require students to make an effort to solve the problem - we don't just hand-out answers. So - what have you tried? What equations do you know for how springs work?
