Q9. Pressure inside a water droplet is given by the relation
Q10. The coefficient of lateral friction for equilibrium super elevation is taken
Sol. The total solids in water are due to the presence of suspended solids and dissolved solids.
Depreciation is the lost value of property due to it’s use or wear & tear.
Annual depreciation = (C-S)/n
C = Total cost
S = scrap value
n = Design life of structure.
Sol. For a good brick when kept immersed in water for 24 hours, water absorption should not be more than 20% of its dry weight.
Sol. Perennial canal provide constant and continuous water supply to irrigate the crops throughout the year.
Sol. Transiting ⇒ Revolving the telescope through 180° in a vertical plane about the horizontal axis Is called transiting of theodolite.
Section Modulus (Z) = (Moment of Inertia (I))/(Depth of the neutral axis (y))
