  3. Outline • 1. Engineering Mechanics • 2. Fundamental Concepts • 3. General Principles • 4. Static Analysis • 5. Dynamic Analysis • 6. Future Studies

  4. 1. Engineering Mechanics • Mechanics : - Rigid-body Mechanics - Deformable-body Mechanics - Fluid Mechanics • Rigid-body Mechanics : - Statics - Dynamics

  5. 1. Engineering Mechanics • Statics – Equilibrium Analysis of particles and bodies • Dynamics – Accelerated motion of particles and bodies KinematicsandKinetics • Mechanics of Materials… • Theory of Vibration…

  6. 2. Fundamentals Concepts Basic Quantities • Length, Mass, Time, Force Units of Measurement • m, kg, s, N…(SI, Int. System of Units) - Dimensional Homogeneity - Significant Figures

  7. 2. Fundamentals Concepts Idealizations • Particles – Consider mass but neglect size • Rigid Body – Neglect material properties • Concentrated Force • Supports and Reactions

  8. 3. General Principles - Newton’s Laws of Motion • First Law,Second Law, Third Law • Law of Gravitational Attraction - D’Alembert Principle : F+(-ma)=0 - Impulse and Momentum - Work and Energy - Principle of Virtual Work (Equilibrium)

  9. 4. Static Analysis • Force and Equilibrium • Force System Resultants • Structural Analysis • Internal forces • Friction • Centroid and Moments of Inertia • Virtual Work and Stability

  10. 5. Dynamic Analysis • Kinematics of a Particle • Kinetics: Force and Acceleration • Work and Energy • Impulse and Momentum (Impact) • Planar Kinematics and Kinetics • 3-D Kinematics and Kinetics • Vibrations

  11. 6. Future Studies • 飛機結構設計目標 1. 成本及重量(Cost and Weight) 2. 靜力強度(Static Strength) 3. 耐久性(Durability) 4. 耐損傷性(Damage Tolerance) 5. 耐振顫及振動性(Flutter and Vibration) 6. 耐腐蝕性(Corrosion Resistance) 7. 耐毀損性(Crashworthiness) 8. 維修及製造簡易性
