[QUOTE="BvU, post: 5469564, member: 499340"] This is for the situation as in the video when there is no extra force involved !Ok, so your μ = tanθ + M/(m cosθ) has the right sign and you have a set of observations of M as a function of ##\theta##. You can investigate if ##\mu## depends on ##\theta## (*). But if you want to show that ##\mu = \tan\theta## directly, you'll have to find a way to vary ##\mu## and work with M = 0. (*) ##\mu = \tan\theta## doesn't mean that ##\mu## varies with ##\theta##; it means that the angle at which sliding is about to start has a tangent with a value that is equal to ##\mu##. [/QUOTE]
