Question about Static Friction

Click For Summary

Discussion Overview

The discussion revolves around the concept of static friction, specifically focusing on the minimum force required to initiate motion in an object at rest. Participants explore the relationship between static and kinetic friction and the conditions under which an object begins to move.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant questions whether applying a force equal to the maximum static friction (Fsmax) results in motion or if the object remains at rest.
  • Another participant suggests that understanding the definitions of static and dynamic coefficients of friction is crucial for addressing the original question.
  • A different participant expresses intrigue at the original question regarding static friction, indicating a potential divergence in understanding or perspective.
  • One participant asserts that the static friction force must be overcome to initiate sliding motion, implying a specific interpretation of the mechanics involved.

Areas of Agreement / Disagreement

The discussion contains multiple viewpoints regarding the nature of static friction and the conditions for motion. There is no consensus on the interpretation of the force required to initiate movement.

Contextual Notes

Participants have not provided specific definitions or mathematical formulations for static and kinetic friction, which may limit the clarity of the discussion. The reliance on varying sources for information is noted but not resolved.

Okay, I have been coming across a lot of problems that share something in common; They all ask what is the minimum amount of force required to move the object. Alright, so I've been looking all over the internet and have been finding varying answers from If the Pushing force (P) equals Fsmax, then the object starts moving. Is that true? When you equal Fsmax in force does it change to kinetic friction, hence the motion. Or when it equals Fsmax do you remain at rest? These problems are really annoying me due to the fact I don't know how to set up equations of friction to find the minimal force! Thanks for taking the time to read this! :)

How about you quote us the definitions of the static and dynamic coefficients of friction? And please give us links to where you found the information. Then, if you still have questions after answering your own questions, we will be happy to help.


EDIT -- not trying to sound like a mean guy here. Just wanting to make sure you are using the right search terms in your searches to answer your question, and making sure that you start to get better at answering your own questions using automated Internet search engines. I do it dozens of times a day in my work, and that's what you should be teaching yourself to be able to do...

Never have i heard of such an interesting "view" of static friction.

Well, I think they just mean that the static friction force is what you have to overcome to break an object loose to start it sliding.
