Extracted text: Q2:- The 220-lb crate shown in figure below is being moved by a rope that passes over a smooth pulley. The coefficient of friction between the crate and the floor is 0.28. 1. Assume h = 3.9 ft and determine the force P necessary to produce impending motion. 2. Determine the value of h for which impending motion by slipping and by tipping would occur simultaneously.
