What Is the Maximum Value of Static Friction Coefficient to Move a 10kg Object?

Click For Summary

Homework Help Overview

The problem involves determining the maximum value of the static friction coefficient for a 10kg object that requires a force of 50N to initiate movement from rest. The discussion centers around the relationship between normal force, weight, and static friction.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the relationship between normal force and static friction, questioning how to calculate the normal force and its connection to the object's weight. There are attempts to apply the friction equation, but some express confusion due to multiple unknowns.

Discussion Status

Some participants have provided guidance on the relationship between normal force and weight, suggesting that the normal force is equal to the weight of the object. There is a mix of interpretations regarding the calculation of the static friction coefficient, with some participants proposing potential values based on their reasoning.

Contextual Notes

The discussion reflects uncertainty regarding the calculation of normal force and the application of the static friction equation, with participants navigating through the problem without a definitive consensus on the solution.

The Attempt at a Solution

You'll have to start us out here. What's the normal force and what does the normal force have to do with static friction?
 
Normal force is the force acting up on the object so the higher the normal force the less kinetic friction it takes to get the object moving. I can't find the normal force though.
 
Exactly backwards. Frictional force is related to normal force times the Ms. So larger normal force means more friction. I think you might need to look in a book. How is the normal force related to weight? How is weight related to mass?
 
I was trying to use this equation Ff=FnMs, but there are 2 unknowns so i can't solve for it
 
I think the answer would be .5
Ff=FnMs
50=98Ms
Ms=.5(rounded)
 
You've got it. Fn=mg by balancing the vertical forces.
 
Thank you
