Homework Help: Exam: Measuring the Coefficient of Friction

  1. Oct 20, 2011 #1
    Hi everybody.
    I am going to exam on Monday. I would like to make a experiment on how to measure the coefficient of friction.

    I know, that I can find the mu(s), by taking the tan to the angle α.

    μs = tan(α).

    Is there somebody, who has some others ideas how to measure that? Somebody, who have done the experiment before. Maybe done it in a different way. It shall be university level.

    I don't understand what experiment you are thinking of.
    The usual way to measure μ is to use a force measuring device (spring scale?) to pull on an object. Knowing the force and the mass, you can figure out the μ. No angles involved if you pull horizontally.
