单词	angle of friction
释义	angle of friction The angle λ such that tan λ = μs, where μs is the coefficient of static friction. Consider a block resting on a horizontal plane, as shown in the figure. In the limiting case when the block is about to move to the right on account of an applied force of magnitude P, N = mg, P = F, and F = μsN. Then the contact force, whose components are N and F, makes an angle λ with the vertical. λ is the angle of friction
