Modules
Module 01Resultant of Concurrent Force Systemsexpand

Introduction to Engineering Mechanics-statics-basic principles of statics- principles of superposition and transmissibility, law of action and reaction(review). Free body diagrams. Parallelogram law, equilibrium law. Concurrent coplanar forces-composition and resolution of forces, resultant – methods of projections. Equilibrium – equations. Equilibrant.

Module 02Resultant of Non-concurrent Force Systems, Equilibrium of Rigidexpand

Bodies Non-Concurrent coplanar forces – Varignon’s Theorem of moments. Parallel coplanar forces – couple. Resultant of non-Concurrent coplanar forces. Equilibrium of bodies subjected to general coplanar force system - equilibrium equations. Friction – sliding friction - Coulomb’s laws of friction – analysis of single bodies, ladder friction.

Module 03Centroid and Moment of Inertia, Support Reaction of Beamsexpand

Centroid of composite areas– Moment of inertia-parallel axis and perpendicular axis theorems. Polar moment of inertia, radius of gyration. Support reaction of simple beams subject to concentrated vertical loads and UDL.

Module 04Kinetics of Translationexpand

Mass moment of inertia-ring, cylinder and disc. (Concept only) Dynamics – review of Newton’s Laws –D’Alembert’s principle. – motion on horizontal and inclined surfaces, motion of connected bodies.

Module 05Kinematics and Kinetics of Rotationexpand

Impulse momentum equation and work energy equation (concepts only). Curvilinear translation – Review of Kinematics- kinetics – equation of motion. Rotation – kinematics of rotation- equation of motion for a rigid body rotating about a fixed axis – rotation under a constant moment. Plane motion of rigid body – instantaneous centre of rotation (concept only).
