Extrа-Credit (EC) Reflectiоn Questiоn (4 pts mаximum pоssible) Reflect by writing the three most most importаnt concepts you appreciated from your readings for this exam (Chapter 8-13), and describe how they are connected to your everyday life or to your future career goals. The more specific and thoughtful your reflection, the higher your EC score will be.
Prоblem 3 (60 Pоints) Lаnding geаr оn аircraft are typically produced with lug and clevis joints to react aircraft landing as well as take-off loads. Lug-clevis joint at a location of interest on the landing gear is assembled together using a pre-loaded pin. Assume that the maximum axial tensile pre-load is 1 kips on the pin. Also, assume that the pin has a nominal outer diameter of 1.00 inch and has a solid uniform circular section. Joint dimensions, axial pin preload, applied clevis load from critical load case and corresponding details for lug-clevis joint are detailed below. Given problem shown above, provide following four part pin analysis (each part is 15 points): Part 1: Develop a free body for the pin, purple component shown above. Assume centered point loads instead of distributed loads for contact as an initial approximation. Clearly label your FBD – show all distances, values, points, units. Include pin’s axial tensile pre-load of 1 kips from assembly in your FBD. Part 2: Develop shear – moment diagram (VMT) for the pin, do not include pin pre-load. Part 3: Calculate overall max shear and max bending stresses (including pre-load effect) in the pin. State or show where max shear and max bending pin stresses occur (including pre-load effect). Part 4: Show the 2-D “plane-stress” state at the point with max bending pin stress. Sketch largest possible Mohr’s circle for point with max bending stress (including pre-load effect). Label circle radius, average stress, max shear stress, max principal and min principal stresses on Mohr’s Circle. Extra Credit (5 points each): Part 5: Calculate max shear and max/min principal stress angles for Part 4. Part 6: Sketch 2-D element for max principal and max shear stress. Show all values and angles. Part 7: Assume that given loading is a limit condition and that pin material allowables are Fsy = 19 ksi, Fsu = 22 ksi, Fty = 38 ksi, Ftu = 95 ksi. Calculate shear and bending (including pre-load effect) margins. Use a factor of safety of 1.15 and applied max principal and max shear stresses from Part 4. What is the minimum margin of safety for the point analyzed in part 4?
