Yep, got the answer and it was correct. Thank you for the help

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

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?

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

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...
