2. (18 points) The crate has a mass of 200 kg, and the coefficient of friction between the crate and the inclined plane is 0.35. a. Find the value of P for impending sliding motion up the plane. b. For what range of heights above the plane may this force be applied if clockwise tipping of the crate is not to occur? c. If the force P is removed, will the crate tip over in a counterclockwise sense? d. If the force P is removed, will the crate slide down the ramp? 3
