What is Mechanics?

• Mechanics: Branch of physics considering the action of forces on bodies at rest or in motion.
• Engineering Mechanics: Application of mechanics to engineering problems.
• Divided into:
  • Mechanics of Solids: Solids, subdivided into Rigid Bodies and Deformable Bodies.
  • Mechanics of Fluids: Hydraulics, fluid behavior.
• Rigid Bodies: Assumption of no deformation to simplify calculations.
• Deformable Bodies: Consider deformation for certain calculations.

Branches of Mechanics

1. Statics: Study of forces on bodies at rest.
2. Dynamics: Study of forces and motion.
   • Kinematics: Motion without considering forces.
   • Kinetics: Motion by considering forces.

Engineering Mechanics Syllabus

1. Basic Concepts
   • Forces, moments, vectors, Newton's law, principle of transmissibility, varignon's theorem.
2. Equilibrium
   • Net forces and moments.
3. Friction and its Applications
   • Types and applications of friction (belt, wedge, rolling).
4. Truss and Frames
   • Forces in members of structures.
5. Centroid and Center of Gravity
   • Calculations of centroid, center of mass, center of gravity.
6. Moment of Inertia
   • Area and mass moment of inertia.
7. Kinematics of Particles
   • Study of particles in motion.
