Engineering Mechanics
Definition: Engineering Mechanics deals with the behavior of bodies under the action of forces, covering statics and dynamics principles.
Unit 1: Introduction to Mechanics
- Basic concepts, Laws of mechanics.
- Force systems, Resultant and equilibrium of concurrent and non-concurrent forces.
- Moment and couple, Varignon’s theorem.
Unit 2: Trusses and Frames
- Analysis of perfect trusses – Method of joints, Method of sections.
- Frames and machines.
Unit 3: Friction
- Laws of friction, Angle of friction, Angle of repose.
- Wedge friction, Belt friction.
- Rolling resistance.
Unit 4: Centroid and Moment of Inertia
- Centroid of lines, areas and volumes.
- Moment of inertia of areas – Parallel axis and perpendicular axis theorems.
