Remote Sensing, Engineering Mechanics, and Surveying Basics
Remote Sensing: Definition and Basic Concepts
- Remote Sensing refers to the technique of acquiring information about objects or areas without physical contact, typically via satellites or sensors placed remotely.
- Satellites detect and interpret the energy (rays) reflected or emitted from objects on Earth, such as water bodies, buildings, or vegetation, to provide detailed spatial information.
- This process allows the identification of features like water presence, buildings, and vegetation through the

Two-Way Slab Design Calculations: Steps and Formulas
Step 1: Design Constants
For M20 & Fe415:
τc max = 1.4 N/mm² (from IS:456 Table 73)
σ = 2.76 (used in moment capacity formula)
Step 2: Effective Span Calculation
Slab Type Check
Cy/Cx = 6/4 = 1.5, which is < 2 → Two-Way Slab Panel
Effective Depth Calculation
Using IS 456 empirical formula:
$$\frac{L}{d} = \text{MF} \times \text{BF}$$
Basic factor (BF) = 26
Modification factor (MF) = 1.3
$$d = \frac{L}{\text{MF} \times \text{BF}} = \frac{6000}{1.3 \times 26} = 177.51 \, \text{mm} \approx 180 \, \

Mole and Equivalent Concept Cheat-Sheet
1. Basic Measurements
- Density (ρ): ( ρ = \frac{\text{mass}}{\text{volume}} )
- Mass: ( \text{mass} = ρ \times \text{volume} )
- Volume: ( \text{volume} = \frac{\text{mass}}{ρ} )
- SI Unit: ( \text{kg/m}^3 )
2. Mole Concept and Avogadro’s Number
- Number of Moles (n): ( n = \frac{\text{mass}}{\text{molar mass}} )
- Molar Mass: ( \text{molar mass} = \frac{\text{mass}}{n} )
- Mass from Number of Particles: ( \text{mass} = \left( \frac{\text{Number of particles}}{N_A} \right)
