A crate of weight Fg is pushed by a force P on a horizontal floor.
(a) If the coefficient of static friction is -s and P is directed at angle μ below the horizontal, show that the minimum value of P that will move the crate is given by
(b) Find the minimum value of P that can produce motion when μs = 0.400, Fg = 100 N, and θ = 0°, 15.0°, 30.0°, 45.0°, and 60.0°.
