Finding coefficient of fuzzy block and dynamics cart.

Click For Summary

Homework Help Overview

The discussion revolves around calculating the coefficient of friction between a fuzzy block and a dynamics cart as part of a lab task. Participants are exploring the experimental approach to determine this coefficient.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the use of formulas related to friction but express uncertainty about the necessary variables. There is a focus on whether the coefficient can be found experimentally or if prior calculations are needed. One participant inquires about using a ramp to find the coefficients of friction.

Discussion Status

The conversation is ongoing, with participants sharing their methods and clarifying the experimental nature of the task. Hints about using an inclined plane to determine the coefficients of friction have been suggested, but no consensus or definitive methods have been established yet.

Contextual Notes

Participants mention having all materials for the lab task but express confusion about how to begin. There is an emphasis on the experimental aspect of the assignment, with no requirement for prior calculations or estimations.

Homework Statement


Calculate the coefficient of friction between a fuzzy block and dynamics cart?
This is a Lab task so I have all the materials but I don't know where to start.



Homework Equations


u=ff/fn
uk=fk/fn
us=fs/fn



The Attempt at a Solution


I tried using the formulas but i don't have any of the variables exept fn which is the magnitude of the normal force to an object and so since an object is perpindicular to the surface it is 9.8m/s^2

Welcome to the PF.

Are you allowed to just find the coefficient experimentally, or do you need to calculate/estimate it before doing any experiments?
 
I'm doing it experimentally,I don't have to calculate or estimate anything.

Do you know the simple way to use a ramp and object to find the coefficients of friction?
 
umm no.. enlighten me

Well, this is your assignment, so you need to do the bulk of the work (per the PF rules link at the top of the page).

You've been given the hint that there is an easy way to find one or both of the coefficients of friction between an object and an inclined plane. See if you can use Google to get more hints, or think about the definition of mu...
