Which type of foundation is most suitable for a heavy structure on soft, compressible soil where a firm stratum exists at great depth?
Answer: Pile foundation
Pile foundations transfer load to deep, competent soil or rock when shallow foundations cannot provide adequate support.
In reinforced concrete design, what does the term 'balanced section' refer to?
Answer: A section where concrete crushes and steel yields simultaneously at failure
A balanced section reaches its limiting compressive strain in concrete and tensile yield strain in steel at exactly the same time.
What is the primary purpose of a weir in a water supply or irrigation system?
Answer: To measure or regulate flow and raise the upstream water level
A weir is an overflow structure used to regulate water flow, measure discharge, and maintain upstream head.
According to the AASHTO classification system, a soil classified as A-7 is best described as:
Answer: Highly plastic clay — poor subgrade material
A-7 soils are highly plastic clays or silts considered poor subgrade materials due to high volume change with moisture.
In structural analysis, the degree of static indeterminacy of a fixed-fixed beam is:
Answer: 3
A fixed-fixed beam has three redundant reactions (one pin + two fixed ends provide six reactions, three equilibrium equations leave three redundants).
Which water treatment process is specifically designed to remove dissolved iron and manganese from groundwater?
Answer: Aeration followed by filtration
Aeration oxidizes dissolved iron and manganese to insoluble forms that are then removed by sedimentation and filtration.
What is the critical path in project scheduling (CPM)?
Answer: The sequence of activities with zero total float that determines project duration
The critical path has zero float, meaning any delay on it directly delays project completion.
