GAT Subject Engineering MCQs

Traffic volume is commonly expressed as vehicles per hour or per day.
It supports capacity, design, and planning decisions.

The Proctor test establishes the moisture-density relationship for soil.
Its results guide field compaction control.

Permeability depends on particle size, void ratio, and fluid properties.
Sands are generally more permeable than clays.

Retaining walls hold back soil at different elevations.
They must be checked for sliding, overturning, and bearing failure.

Wall movement away from soil allows the active condition to develop.
Active pressure is lower than at-rest pressure.

A theodolite measures horizontal and vertical angles.
Modern total stations combine angle measurement with electronic distance measurement.

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.
