Question 1

In retaining wall design, what is the primary purpose of a drainage layer or weep holes?

Accepted Answer

To relieve hydrostatic pressure behind the wall

Answer

Drainage layers and weep holes relieve hydrostatic pressure that would otherwise add significant lateral force to the retained soil pressure.

Question 2

The Hazen-Williams equation is used to calculate:

Accepted Answer

Head loss due to friction in pressurized pipe flow

Answer

The Hazen-Williams equation estimates friction head loss in full-flowing pressurized pipes using an empirical roughness coefficient C.

Question 3

Which concrete mix property is measured by the slump test?

Accepted Answer

Workability

Answer

The slump test measures the workability (consistency) of fresh concrete by recording how much a concrete cone settles after the mold is removed.

Question 4

A two-span continuous beam has a uniformly distributed load. Compared to a simply supported beam of the same span, the maximum positive bending moment in the continuous beam is:

Accepted Answer

Smaller because the interior support reduces midspan moment

Answer

Interior supports in continuous beams create negative moments that reduce positive midspan moments compared to simply supported beams.

Question 5

In soil mechanics, the coefficient of consolidation (Cv) is used to predict:

Accepted Answer

Rate of settlement in saturated clay

Answer

Cv governs the rate at which excess pore water pressure dissipates and primary consolidation settlement occurs in saturated fine-grained soils.
