The coefficient of static friction is the tangent of the critical angle θc when the block starts to slide.
μs = tanθc = tan(40°) = 0.839

asked 02/22/20A block rests on an inclined plane. Its angle with the horizontal is increased. When the angle becomes 40 ̊, the block starts to slide. Calculate the coefficient of static friction between the block and the plane.
