How do i find applied force if it not given?

Click For Summary

Homework Help Overview

The discussion revolves around finding the applied force, force of friction, and coefficient of friction in various scenarios, particularly when certain values are not provided. The subject area includes dynamics and frictional forces.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the need to resolve forces and identify normal forces, while questioning the feasibility of finding certain values without given coefficients. There are inquiries about how to approach problems involving multiple surfaces and the necessary variables to consider.

Discussion Status

The conversation is ongoing, with some participants suggesting that without specific coefficients or equations, finding solutions may not be possible. Others encourage clarifying the question to facilitate more targeted assistance.

Contextual Notes

Participants note the lack of specific information regarding coefficients of friction and the nature of the surfaces involved, which may impact the ability to solve the problems presented.

how do i find applied force if it not given?
how do i find force of friction if coefficient of friction is also not given?
how do i find coefficient of friction of objects on 3 different surfaces?
(what should be the variable?)
thanks so much

the way is same, resolve the forces, get the normal. if co-oefiicient is not given, its very simple, you can't find. for three surface, if there are less than 3 equations, then the solution is also simple. you can't help.
 
make your question a bit clearer. frame it in a for of sum

The particulars of how you'd solve for applied force, or friction, or the coefficient of friction depend on the exact problem. But usually it will involved applying Newton's laws and the simple model of friction in terms of [itex]\mu[/itex] and normal force.

Pick a specific problem and give it a try.
