The spur gear has a pitch radius of 2.5 in. (Figure P4.12). During ageartrain’s operation, a 200-lb meshing force acts at 25° relative to horizontal.Determine the moment of that force about the center of the shaft. Use the(a) perpendicular lever arm and (b) moment components methods. Comparethe answers of the two methods to verify the accuracy of your work.
