Analysis of surveying steps:

• Study of geology of area: Specialized secondary investigation.
• Field mapping of area: Executed after survey control stations are established.
• Reconnaissance surveying of area: The vital preliminary field reconnaissance survey enables the surveyor to examine the terrain, select suitable traversing stations, and plan the route before detailed measurements begin.
• Observing relief of area: Part of the broader reconnaissance phase.

Properties of pure water at $25\,^\circ\text{C}$ ($298.15\text{ K}$):

• Density of water at $25\,^\circ\text{C}$: Exactly $997.05\text{ kg/m}^3$ (CRC Handbook: $997.047\text{ kg/m}^3 = 0.99705\text{ g/cm}^3$), which rounds to approximately $1000\text{ kg/m}^3$ in general agricultural hydraulics.
• Dynamic viscosity (\(\mu\)): Approximately $0.890\times 10^{-3}\text{ Pa}\cdot\text{s}$ ($0.89\text{ cP}$).
• Surface tension: Approximately $0.07197\text{ N/m}$.
• Specific weight (\(\gamma\)): $\gamma = \rho g = 997.05 \times 9.807 \approx 9778\text{ N/m}^3$ ($9.78\text{ kN/m}^3$).

Analysis of mouldboard plough components:

• Share: Makes the forward horizontal cut into the soil and lifts the furrow slice.
• Land side: Resists side thrust and balances the plow against the unploughed furrow wall.
• Frog: Central structural casting to which the share, mouldboard, and landside are bolted.
• Mould board: The curved steel wing that receives the soil slice lifted by the share, turns it over, pulverizes it, and inverts it completely into the adjacent furrow to bury surface weeds and stubbles.

Analysis of agricultural workshop tools:

• Making and measuring: A sliding bevel square (or bevel gauge) is a layout tool with an adjustable blade used in carpentry and farm workshops for marking, laying out, measuring, and transferring angles (other than 90°).
• Cutting: Saws and chisels are cutting tools.
• Planing: Done using hand planes (jack plane).
• Striking: Hammers and mallets are striking tools.
