Yantriki (Mechanics) | B.A./B.Sc. IV Semester DSE | NEP 2020 | Chhattisgarh State Universities | Useful for UPSC & IFS Mathematics Optional | Dr. H.K. Pathak

Yantriki (Mechanics) by Dr. H.K. Pathak — Published by Shree Shiksha Sahitya Prakashan, Meerut

Strictly as per the NEP 2020 Discipline Specific Elective (DSE) syllabus for B.A./B.Sc. Fourth Semester, written for students across India — with particular relevance for Chhattisgarh State Universities: Pandit Ravishankar Shukla University (PRSU) Raipur, Hemchand Yadav Vishwavidyalaya Durg, Guru Ghasidas Vishwavidyalaya Bilaspur, and Sant Gahira Guru Vishwavidyalaya Sarguja.

CLASSICAL MECHANICS, FULLY IN HINDI: Statics and Dynamics — equilibrium of forces, virtual work, central orbits, Kepler's laws — are rarely explained in Hindi at this depth. This book makes rigorous mechanics accessible to Hindi-medium students nationwide, not just in Chhattisgarh.

SYLLABUS COVERAGE (4 Units, 60 Periods):

Unit I: Analytical conditions of equilibrium of Coplanar Forces; Forces in three dimensions; Poinsot's central axis; Wrenches; Null lines and planes

Unit II: Virtual work; Stable and Unstable equilibrium; Catenary

Unit III: Velocities and accelerations along tangential, normal and transverse directions; Simple Harmonic Motion; Motion under other laws of forces; Elastic strings

Unit IV: Motion in resisting medium; Constrained motion; Motion on smooth and rough plane curves; Motion of particles of varying mass; Central orbit; Kepler's laws of motion; Rocket motion; Motion of particle in three dimensions

ALSO USEFUL FOR UPSC CIVIL SERVICES & IFS MATHEMATICS OPTIONAL: Nearly the entire Dynamics & Statics section of UPSC Mathematics Optional Paper I is covered here — rectilinear motion, SHM, constrained motion, motion under resistance, motion of varying mass, Kepler's laws and central orbits, virtual work, common catenary, and equilibrium of forces in three dimensions. IFS (Indian Forest Service) Mathematics Optional shares the same syllabus.

EXAM PREPARATION FEATURES: Previous Year Solved Papers | Objective Type Questions | Multiple Choice Questions (MCQs) | Higher Order Thinking Skills (HOTS)

Teacher-recommended, and known for university exam questions drawn directly from its worked examples. Also available in English medium as 'Mechanics' by the same author. Written by Dr. H.K. Pathak — a trusted author in Indian mathematics education.
