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...

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!
