    Finding the angle where a box on an inclined ramp starts to slip

    Yes, thanks for the reminder. That's one of those things that you end up smacking yourself in the head.

    Finding the angle where a box on an inclined ramp starts to slip

    In this equation both mg are the same correct? So that would make μcosθ=sinθ I realize looking at this that I can't just factor out that angle. Is there a way to determine at what angle the book is no longer stationary short of plugging in random angles?

    Finding the angle where a box on an inclined ramp starts to slip

    Thank you for the quick response (sorry for my delay). So what does the symbol "μ" represent in the equation? Will I be able to set the equation equal to zero and factor out the common angle? Thanks, Rob

    Finding the angle where a box on an inclined ramp starts to slip

    Homework Statement A box of textbooks of mass 24.5 rests on a loading ramp that makes an angle with the horizontal. The coefficient of kinetic friction is 0.260 and the coefficient of static friction is 0.360. As the angle is increased, find the minimum angle at which the box starts to...
