About this book
Mechanics (Statics & Dynamics) by Dr. H.K. Pathak covers all four units of the 60-period NEP 2020 Discipline Specific Elective (DSE) syllabus for B.A./B.Sc. Fourth Semester, in university sequence.
The syllabus overlaps genuinely with the Mechanics section of the UPSC and IFS Mathematics Optional paper — Poinsot's central axis, wrenches, virtual work, central orbits, Kepler's laws and motion in a resisting medium all appear there. Students preparing for those exams get a head start from the same book.
Also available fully in Hindi as Yantriki, which is rare for this subject. Written for all Chhattisgarh State Universities. Published by Shree Shiksha Sahitya Prakashan, Meerut.
