Can You Pass This Civil Engineering Exam? Trivia Questions Quiz

The bearing capacity of soils can be improved by increasing the depth of footing, draining the subsoil water, and ramming granular material like crushed stone into the soil. Increasing the depth of the footing spreads the load over a larger area, reducing the pressure on the soil. Draining the subsoil water helps to increase the soil's strength by reducing its water content. Ramming granular material into the soil improves its compaction and stability, increasing its bearing capacity. Therefore, all of these methods can contribute to improving the bearing capacity of soils.

Hard rocks have the highest maximum bearing capacity compared to other types of soil. This is because hard rocks are compact and dense, providing strong support for structures and heavy loads. On the other hand, black cotton soil, dry coarse sandy soil, and fine sandy soil have lower bearing capacities due to their loose and less stable nature. Therefore, hard rocks are the most suitable for supporting heavy structures and loads.

Both the seismic method and electrical resistivity method are commonly adopted geophysical methods in civil engineering. The seismic method involves the use of seismic waves to investigate the subsurface structure and properties of the Earth, which is useful for assessing the stability of soil and rock formations. The electrical resistivity method, on the other hand, measures the electrical resistivity of the subsurface materials, providing information about their composition and moisture content. Both methods are valuable in civil engineering for determining the suitability of sites for construction, detecting underground structures, and assessing the potential for geological hazards.

Black cotton soil is unsuitable for foundations due to its property to undergo a volumetric change due to variation of moisture content. This means that the soil expands when it absorbs water and shrinks when it dries out. These changes in volume can lead to significant movement and settlement of the soil, which can cause damage to the foundation of structures. Therefore, it is not recommended to build foundations on black cotton soil.

When the walls are subjected to heavy loading and the bearing capacity of the soil is very low, a reinforced concrete footing is constructed. This is because reinforced concrete footings provide additional strength and stability to support the heavy load and distribute it evenly to the soil. The reinforcement in the footing helps to prevent any potential failure or settlement of the wall due to the low bearing capacity of the soil. Therefore, a reinforced concrete footing is the most suitable choice in this scenario.

The correct answer is "are vertical wooden members." This means that the studs of a common wooden partition are the vertical wooden members. Studs are typically used to provide structural support and stability to the partition. They are placed vertically and are usually spaced evenly apart to create a framework for the partition.

When carbon content is less than 0.1%, steel is referred to as dead steel. This is because the low carbon content makes the steel less reactive and less prone to changes in its microstructure. Dead steel is often used in applications where high ductility and formability are required, such as in the manufacturing of automotive parts or appliances.

A brick that is cut across the width is called a "bat". This term is commonly used in masonry and construction to refer to a brick that has been cut in half. The cut is made perpendicular to the length of the brick, resulting in two shorter pieces that are often used for special purposes such as creating a decorative pattern or fitting into a tight space. The term "bat" is derived from the Old English word "bæt," which means a short stick or club.

Roman civil engineers were known for their advanced engineering skills and innovative construction techniques. They were responsible for building impressive structures such as harbors, insulae (apartment buildings), and aqueducts. However, stadiums were not specifically associated with Roman civil engineers. While the Romans did construct amphitheaters and arenas for various events, the design and construction of stadiums were not considered a unique specialty of Roman civil engineers. Therefore, the correct answer is Stadium.

Using ribbed or steel bars does not have a disadvantage of high labor charge. This means that the cost of labor required for using these bars is not significantly higher compared to other options.
