The figure shоws а unifоrm crаte resting оn а horizontal surface. The crate has a square cross section and a weight of W = 580 N, which is uniformly distributed. At the bottom right edge of the surface is a small obstruction that prevents the crate from sliding when a horizontal pushing force P is applied to the left side. However, if this force is great enough, the crate will begin to tip and rotate over the obstruction. (a) What causes the tipping—the force or the torque that it creates? Explain your answer. (5 points) (b) Where should P be applied so that a minimum force will be necessary to provide the necessary torque? In other words, should the lever arm be a minimum or a maximum? Explain your answer. (10 points) (c) Determine the minimum pushing force that leads to tipping. (10 points) Show all work and write your answer on your paper and upload it to Gradescope at the end of the exam.
