In reinforced concrete design (ACI 318), the minimum concrete cover for reinforcement in a slab exposed to weather is typically:
Answer: 1.5 inches
ACI 318 requires 1.5 inches of cover for slabs, walls, and joists not exposed to weather when bar size is #5 or smaller.
Which hydrograph method estimates the runoff response of a watershed to a unit rainfall excess?
Answer: Unit hydrograph method
The unit hydrograph represents the direct runoff hydrograph resulting from one inch of rainfall excess uniformly distributed over the watershed.
Mohr's circle is used in structural and geotechnical engineering to graphically determine:
Answer: Principal stresses and shear stresses at a point
Mohr's circle graphically represents the state of stress at a point, allowing determination of principal stresses and maximum shear stress.
A retaining wall that relies on its own weight to resist overturning is called a:
Answer: Gravity retaining wall
Gravity retaining walls use their large self-weight (mass) to resist the lateral earth pressure without relying on reinforcement.
In open channel hydraulics, critical flow occurs when the Froude number equals:
Answer: 1.0
At critical flow, Fr = 1, indicating the flow transitions between subcritical (Fr 1) regimes.
The 'slump test' for fresh concrete primarily measures:
Answer: Workability (consistency)
The slump test measures the consistency or workability of fresh concrete by recording how much a cone-shaped sample slumps.
Which type of surveying method uses the angles and distances from a single control point to locate features?
Answer: Radiation (polar) method
The radiation method sets up an instrument at one station and locates surrounding points by measuring angles and distances from that point.
