12 Mechanics Mechanics Rijid Body Mechanics Non-Rigid Body Mechanics Fluid Mechanics Statics (Stationary or constant velocity particles/bodies) Dynamics (Bodies in accelarated motion) Elasticity Plasticity Mechanics of Materials Kinematics (deals with geometric aspects of motion) Kinetics (deals with forces causing the motion) As one of the branches of physical sciences, mechanics is concerned with the state of rest or motion of bodies subjected to action of forces. 12/144

13 Fundamental Definitions in Mechanics A(x 1,y 1,z 1 ) Position: Location of bodies in space. Time: Duration in motion. Mass: Resistance of body to action. Force: Effect of one body on another. S, t B(x 2,y 2,z 2 ) 13/144

14 Supplementary Concepts in Mechanics Particle (Maddesel Nokta) has a mass but negligible size and shape Rigid Body: Body that does not deform under the action of forces Scalar: It has a numerical value. Vector: It has direction and magnitude P:75-78 cm, R: 12,3 cm, m: g 14/144
