Spring stretched by weight, find spring constant

Click For Summary

Homework Help Overview

The discussion revolves around a physics problem involving a spring subjected to weights. The original poster presents a scenario where a 60-pound weight stretches a spring by 3 inches and poses questions about the stretch caused by a 30-pound weight and the calculation of the spring constant.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants question the assumption made regarding the stretch of the spring with the 30-pound weight and seek clarification on the definition of the spring constant. There is also a prompt to identify relevant equations that relate force and spring length.

Discussion Status

The discussion is active, with participants engaging in questioning assumptions and seeking deeper understanding of the concepts involved. Guidance has been offered regarding the need to reference relevant equations, indicating a productive direction in the conversation.

Contextual Notes

There is mention of a template for posting questions that includes a request for relevant equations, which may influence how participants approach the problem.

I'm in a basic level physics class as a requirement for my major. Physics has never been a strong subject for me. Can someone help me with this problem?
You have a spring with a 60lb weight hanging from it.

A) If the 60 pound weight stretches the spring 3 inches, how much will a 30 pound weight stretch the spring?

**I'm assuming the answer is 1.5 inches??

B) what is the spring constant(k) of the spring? Be sure to include the correct units of k.

Why did you make that assumption?
What have you done to solve the problem?
How is "spring constant" defined in your text?
No need to make excuses on your ability when asking for help, as it doe neither you or the one helping you any good wrt the problem at hand.

That's correct but can you explain why?

B) what is the spring constant(k) of the spring? Be sure to include the correct units of k.

There is a template for posting questions in the homework section and that contains a clue. It asks you to list Relevant Equations. So, what's the relevant equation that relates the length of a spring to the force on it?
