Q6. A cantilever beam is deflected by due to load P if load is doubled, then deflection compared to earlier case will be changed by a factor of:
Sol. Limit state of serviceability
Sol. Trickling filter is attached aerobic growth system and biological process takes places in trickling filters.
Sol. Primary consolidation – Due to expulsion of pore water.
Secondary consolidation – Due to plastic rearrangement of soil solid.
Sol. There are various steps for the approval of work before construction-
1. Administrative approval
2. Expenditure sanction
3. Technical sanction
4. Appropriation of fund
5. Reappropriation of fund
6. Laps of sanction.
Sol. Discharge velocity (V)=5×10^(-7) m\/sec
Void ratio (e)=0.50
Seepage velocity (V_s )=V/n
Sol. Deflection when cantilever beam is subjected to load P
Deflection, when load is doubled,
