### ✅ Why this document is valuable
Mechanics of Materials is a fundamental engineering subject. Every structure, machine, or mechanical system—whether a high-rise building, crane boom, automobile chassis, machine shaft, bolt, beam, or pipe—is designed based on the principles explained in this document.

This document teaches you how to:
- Determine internal forces generated within structural members.
- Understand stress—normal stress, shear stress, and torsional stress.
- Analyze deformation of materials due to axial loads, torsion, bending, and temperature changes.
- Predict failure due to creep, fatigue, yielding, or fracture.
- Apply engineering design safety factors.

Each topic is supported by carefully curated diagrams, mathematical derivations, and solved engineering examples, making it easy to apply theory in real-world design.

### 📘 Content Overview (High-Level)
**Chapter 1 – Stress**
- Internal force types (normal, shear, bending moment, torsional moment)
- Resultant internal loadings using free-body diagram and method of sections
- Average normal and shear stress, tension and compression concepts

**Chapter 2 – Strain**
- Normal and shear strain
- Strain components and deformation measurement
- Small strain theory, displacement & average strain problems

**Chapter 3 – Mechanical Properties of Materials**
- Stress–strain diagram (elastic, plastic, strain hardening, fracture)
- Young's modulus, yield strength, ductile vs brittle materials
- Poisson’s ratio, modulus of resilience, modulus of toughness
- Failure due to creep and fatigue

**Chapter 4 – Axial Load**
- Elastic deformation & superposition method
- Statically determinate and indeterminate axial members
- Thermal stresses and expansion
- Stress concentration

**Chapter 5 – Torsion**
- Torsion formula: τ = Tρ / J and angle of twist φ = TL / JG
- Power transmission via shafts
- Solid vs hollow shafts and stress distribution

**Chapter 6 – Bending**
- Shear force and bending moment diagrams
- Flexure formula: σ = Mc/I
- Neutral axis and strain distribution during bending

Throughout the PDF, actual engineering photos (bridge piers, rotating shafts, beams, bolts, drilling machines) are included to connect theory with real applications.
