Problem 5(5 pts) Refer to the figure to the right for: Determine the minimum horizontal force P required to hold the crate from sliding down the plane. The crate has a mass of 70kg and the coefficient of static friction between the crate and the plane is 5=0.375. Use 45 instead of 30. P= Problem 6 (5 pts) Refer to the figure in problem 5 above for: Determine the minimum horizontal force P required to push the crate up the plane. The crate has a mass of 70kg and the coefficient of static friction between the crate and the plane is s =0.375. Use 45 instead of 30. P=15/1N1 Problem 7 (5 pts) Refer to the figure in problem 5 above for: A horizontal force of P=151N is just sufficient to hold the crate from sliding down the plane, and a horizontal force of P=466N is required to just push the crate up the plane. determine the coefficient of friction, s, between the plane and the crate, and find the mass of the crate. s=mcrate=
