How do you use the angle of uniform slip to calculate coefficient of static friction

  1. How do you use the angle of uniform slip to calculate the coefficient of static friction?
    Is there an equation for this? I cannot find it in the module on friction provided with the course.... thanks!

    I found somewhere that tanθ=μk, but that doesn't really help me, as i am looking for μs! thanks :)

    PS sorry if this is a really stupid question by the way...

    welcome to pf!

    hi tratata! welcome to pf! :smile:

    (try using the X2 button just above the Reply box :wink:)
    it's tanθ = μs (different θ, of course!), and for the same reason

    i suppose you can prove why? :wink:

    Thank you so very much tiny-tim! I really appreciate your help with this! It makes sense now when you pointed out the difference in angle!
