Agricultural Engineering Soil Mechanics Notes1. Agricultural Engineering Fundamentals of Soil Mechanics- Definition and scope of soil mechanics in agricultural engineering
- Physical properties of soil: texture, structure, and consistency
- Classification of soil: particle size distribution, soil types, and their characteristics
- Soil water: capillary rise, soil moisture content, and soil water potential
- Soil compaction: causes, effects, and methods of control
2. Agricultural Engineering Stress and Strength- Stress in soil: definition, types, and calculation
- Strength of soil: shear strength, cohesion, and angle of internal friction
- Factors affecting soil strength: moisture content, density, and stress history
- Mohr-Coulomb theory: failure criteria for soils under different conditions
- Laboratory and field tests for determining soil strength
3. Agricultural Engineering Compaction, Seepage, and Consolidation of Soil- Soil compaction: compaction theories, compaction curves, and compaction methods
- Seepage in soil: Darcy's law, hydraulic conductivity, and flow nets
- Consolidation of soil: primary consolidation, secondary consolidation, and settlement analysis
- Consolidation tests: oedometer test, consolidation test, and determination of consolidation characteristics
4. Agricultural Engineering Earth Pressure, Slope Stability, and Soil Exploration- Earth pressure on retaining walls: active and passive earth pressures, Rankine's theory
- Stability of soil slopes: factors affecting slope stability, slope stability analysis
- Soil exploration: methods of soil sampling, in-situ testing, and laboratory testing
- Soil mechanics in agricultural engineering applications: design of foundations, earthworks, and irrigation systems
