Sol. → Per-oxy Acetyl nitrate is a secondary air pollutant
→ Ringelmann chart is used to grade density of smoke
→ Pneumoconiosis is a disease caused due to coal dust in lungs.
Sol. in design of lacing system for a built-up steel column, the maximum allowable slenderness ratio of a lacing bar is 145.
Sol. Generally, the brick work is measured in terms of m³. but in case of honey comb brick work, brick flat soling, half brick wall or partition wall then, it is measured in m².
Sol. Minimum reinforcement.
For mild steel bar → 0.15% of gross area
For HYSD bar → 0.12% of gross area
Sol. Flexural tensile strength = 0.7 √fck
= 0.7 √25
Co-efficient of uniformity (Cu) = D_60/D_10
Sol. The purpose of conducting the resection method in the plane table surveying is to determine the location of the instrument point.
Length of transition curve (L_s) = 80 m
Radius of the curve (R) = 320 m
Shift(s) = (L_s^2)/24R
= 0.83 m
Sol. In a linear reservoir, outflow rate varies linearly with storage.
Sol. Every material obeys hook’s law within its limit of proportionality.
According to Hooke’s law, stress (σ) α strain (∈)
E= Modulus of elasticity
