본문내용

1-1 Mechanics
⇨ Physical science that deals with the response of bodies to the action of forces

① Statics : Rigid body motion by balanced force (Equilibrium of bodies)
• at rest
• at uniform motion

② Dynamics : concerns with the motion of bodies
• Kinematics : the geometry of motion
⇨ related to the motion of machine elements

• Kinetics : rigid body motion by unbalanced forces
⇨ nonuniform or accelerated motions

* Fluid mechanics : deals with liquid or gases
