 STATICS - CASE STUDY Introduction Problem Animation Click to view movie (735k) Engineers need to test the wing of a new aircraft before actual flight testing. To simulate the lift force during flight, a hydraulic jack applies a force of 4,500 lb at on the wing. What is known: The wing weight is 165 lb/ft. The wing length is 54 ft. The hydraulic point load is 4,500 lb, and is located 49 ft from the wing root. Force Diagram Question What is the maximum shear and bending moment for this loading condition? Approach Replace the distributed wing weight load with an equivalent point load. Determine the reactions for the equivalent system. Develop the shear and moment diagrams with the distributed load in place.
