SUMMARY

The coefficient of kinetic friction (µ) for a pulley can be determined using the formula F = µN, where F represents the force overcoming friction and N is the normal force. In this discussion, a mass of 0.019 kg is mentioned, and the normal force is calculated as 0.20 kg multiplied by 9.8 m/s², resulting in a normal force of 1.96 N. To find µ, one must rearrange the formula to µ = F/N, ensuring that the force F is accurately measured as the force required to overcome friction.

PREREQUISITES
  • Understanding of Newton's laws of motion
  • Basic knowledge of friction and its coefficients
  • Ability to perform calculations involving mass and force
  • Familiarity with the concept of normal force
NEXT STEPS
  • Learn how to calculate normal force in various scenarios
  • Explore the principles of static vs. kinetic friction
  • Study the effects of different materials on friction coefficients
  • Investigate experimental methods for measuring friction in pulleys
USEFUL FOR

Students in physics, engineers working with mechanical systems, and anyone involved in experiments related to friction and pulleys will benefit from this discussion.

How do I find the coefficient of kinetic friction for a pulley?
F=mueN
If a mass of 0.019 kg overcomes the friction in a pulley, is this mue?
Normal force would be 0.20 kg * 9.8?

But it can't be mue, because I am asked to find mue in the question.

Hi sugarntwiligh! :smile:

(have a mu: µ :wink:)

What is the set-up? :confused:

Can you tell us the full question? :smile:
