Coefficient of static friction

Click For Summary

Homework Help Overview

The discussion revolves around determining the coefficient of static friction required for a car to navigate a banked curve without skidding, given specific speeds and a radius. The problem involves concepts from dynamics and friction in circular motion.

Discussion Character

  • Mixed

Approaches and Questions Raised

  • Participants explore the relationship between banking angle, speed, and frictional force, with attempts to derive equations related to centripetal force and friction. Some participants express confusion regarding the setup of forces acting on the car, including normal force and friction.

Discussion Status

There is an ongoing exploration of the forces involved in the scenario, with various participants attempting to clarify the equations and relationships between them. Some have provided partial calculations and interpretations, while others are seeking further clarification on specific aspects of the problem.

Contextual Notes

Participants are working under the constraints of a homework assignment, which may limit the information available and the methods they can use. There is a noted lack of consensus on the correct approach and calculations, with multiple interpretations being discussed.

I am getting 0.29
0.85 = [ 0.405 + μ*0.914]/[0.914 - μ*0.405]
Now solve for μ.

You r correct. The correct answer is 0.296. Thanks so much for your help! ;)
