ASSIGNMENT 4 Textbook Assignment: "Aircraft Basic Construction," chapter 4, pages 4-1 through 4-22. 4-1. What are the most important factors in aircraft construction? 1. Lightness and strength 2. Strength, weight, and reliability 3. Maneuverability and speed 4. Speed, strength, and weight 4-2. The weight of the aircraft is primarily a product of what force? 1. Lift 2. Thrust 3. Gravity 4. Drag 4-3. All stresses imposed on the aircraft wings are transmitted to what area? 1. The fuselage structure 2. The outer layer or shield of the wings 3. The surrounding atmosphere 4. The stress releaser plugs 4-4. A study of each load or stress that is imposed on an aircraft is known by what term? 1. Load and stress configuration 2. Load and stress reaction 3. Dynamic analysis 4. Stress analysis 4-5. Load and stress imposed upon an aircraft must first be analyzed when the aircraft is in what stage of the manufacturing cycle? 1. Final assembly 2. Design 3. Initial flight test 4. Acceptance by Navy 4-6. What aircraft stress results from squeezing of a material? 1. Compression 2. Tension 3. Torsion 4. Bending 4-7. What aircraft stress results from two fastened materials that tend to separate? 1. Tension 2. Bending 3. Torsional 4. Shear 4-8. What aircraft stress results from a twisting force? 1. Compression 2. Bending 3. Torsional 4. Shear 4-9. A reaction to engine torque creates what type of stress in an aircraft fuselage? 1. Bending 2. Tension 3. Compression 4. Torsional 4-10. What primary force is at work on the fuselage when an aircraft is at rest? 1. Torsion 2. Tension 3. Bending 4. Compression 4-11. What is the result of the action of lift forces against the wings of an aircraft in flight? 1. Tension on the bottom and compression on the top 2. Compression on both the bottom and top 3.
