GAT Subject Engineering MCQs

Leveling establishes relative heights of points.
It is used for roads, drainage, buildings, and contouring.

Benchmarks provide elevation control for surveys.
Temporary benchmarks may be established from permanent references.

Contours represent ground relief on maps.
Their spacing indicates the steepness of terrain.

A total station integrates a theodolite, EDM, and onboard computing.
It speeds coordinate and topographic surveys.

An isolated footing supports one column and spreads its load.
Its size depends on column load and allowable soil pressure.

Camber sheds rainwater from the pavement surface.
Its value depends on surface type and rainfall.

A raft or mat distributes loads over a broad area.
It is useful where soil bearing capacity is low or columns are closely spaced.

Superelevation helps balance lateral acceleration on curves.
It improves comfort and reduces skidding and overturning risk.

Piles carry loads through end bearing, shaft resistance, or both.
They are used when near-surface soils are weak.

Stopping sight distance includes perception-reaction distance and braking distance.
It is a fundamental geometric-design requirement.

The slump test provides a quick indication of consistency and workability.
It is widely used for ordinary concrete in the field.

Curing allows cement hydration to continue.
Proper curing improves strength, durability, and crack resistance.
