Chapters

Built to the UPSC ESE (IES) blueprint — notes, shortcuts, solved PYQ-style examples and practice in every chapter.

1Strength of Materials and Structural AnalysisStress, strain and elastic constants, bending and shear in beams, torsion, deflection, columns and Euler buckling, combined stress and Mohr's circle; then determinacy, trusses, influence lines, slope-deflection, moment distribution and arches.⏱ 8 min read

2Reinforced Concrete, Prestressed Concrete and Steel DesignLimit state design to IS 456: the stress block, balanced and under-reinforced sections, shear, development length, slabs and columns; prestressing and its losses; and IS 800 steel design: plastic moment, bolts, welds and compression members.⏱ 8 min read

3Geotechnical Engineering and FoundationsSoil phase relations and index properties, classification, compaction, permeability and seepage, effective stress and consolidation, shear strength, earth pressure, bearing capacity, pile foundations and slope stability, with worked numerical examples.⏱ 8 min read

4Hydraulics, Hydrology and Irrigation EngineeringHydrostatic force, Bernoulli and pipe losses, open-channel flow with Manning, specific energy and the hydraulic jump, rainfall-runoff and the rational method, flood frequency, duty and delta, canal design theories, gravity dams and diversion works.⏱ 8 min read

5Transportation and Environmental EngineeringHighway geometric design (stopping and overtaking sight distance, superelevation, curves), pavement design, traffic flow and railway basics; then water demand and treatment, sedimentation, disinfection, BOD kinetics, wastewater treatment and solid waste.⏱ 7 min read
