Tension from string upon a rock

Click For Summary

Homework Help Overview

The problem involves two 3 kg masses attached to a string, positioned at different radii from a pivot point, and swung in a circular motion. The question focuses on determining the relationship between the tension in the string at the two different points where the masses are located.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants are questioning the configuration of the masses and whether they are connected in a specific manner. There is also a focus on understanding the forces acting on a mass in circular motion.

Discussion Status

The discussion is ongoing, with participants seeking clarification on the setup of the problem and exploring the implications of the hint provided regarding working with proportions. No consensus has been reached yet.

Contextual Notes

There is a lack of detailed information regarding the connection between the masses and the specific forces acting on them, which may affect the analysis of the tension in the string.

Homework Statement


Two 3 kg masses are attached to a string at r1=.5m and r2=1.5m from where the string is held in your hand. You swing them around together at 2 revolutions per second, each of them. The tension holding mass 2 (the distant part of the string) is what fraction of the tension near your hand?


Homework Equations



No Idea.

The Attempt at a Solution

Welcome to PF.

Are the blocks tied together in some way?

Like head to tail?
 
Thanks.

That is all the information I received on the question.
A hint that was given was:[Hint: you can work in proportions without having to numerically solve for either of the centripetal forces required on the two masses]
 
I read it more carefully. Apparently it is tied to the same string at each of the 2 radii.

What is the force of a single mass at some radius rotating in a circle?
