Questions and Answers
1.
A very hard building material made by mixing together cement, sand, small stones and water is
A.
Brick
B.
Concrete
C.
Iron
D.
Stone
Correct Answer
B. Concrete
Explanation Concrete is a very hard building material made by mixing together cement, sand, small stones, and water. It is commonly used in construction due to its durability, strength, and versatility. The combination of these ingredients creates a solid and stable structure that can withstand heavy loads and various weather conditions. Unlike bricks, iron, or stone, concrete is not a natural material but rather a man-made composite that can be molded into different shapes and sizes. Its widespread use in construction projects makes it the correct answer in this context.

2.
Masonry composed of rectangular units of burned clay or shale, or stone is
A.
Concrete
B.
Rubble
C.
Ashlar masonry
D.
Brick
Correct Answer
C. Ashlar masonry
Explanation Ashlar masonry refers to a type of construction where rectangular units of burned clay or shale, or stone are used. This type of masonry involves carefully cut and dressed stones that are laid in regular courses and bonded together with mortar. The precision and uniformity of the stones in ashlar masonry create a smooth and polished appearance. This distinguishes it from other options like concrete, rubble, or brick, which may have a more rough or irregular appearance.

The long face of a brick, usually the face displayed in a wall is the
A.
Stretcher face
B.
Header face
Correct Answer
A. Stretcher face
Explanation The long face of a brick that is usually displayed in a wall is called the stretcher face. The stretcher face is the side of the brick that is laid horizontally in the wall, with the narrow end facing outwards. This face is commonly seen in brick walls and provides the main visible surface of the wall. The header face, on the other hand, refers to the short end of the brick that is visible in a wall when it is laid vertically.

Fastening two pieces of metal together by softening with heat and applying pressure is called
A.
Bending
B.
Welding
Correct Answer
B. Welding
Explanation Welding is the process of joining two pieces of metal together by softening them with heat and applying pressure. This is done by melting the metal at the joint and allowing it to cool and solidify, creating a strong bond between the two pieces. Bending, on the other hand, refers to the process of deforming a metal piece by applying force to it, usually without the use of heat. Therefore, in the given context, the correct answer is welding.

The force that produces strain on a physical body is called
Correct Answer stress
Explanation Stress is the force that produces strain on a physical body. When a physical body is subjected to external forces or pressure, it experiences stress, which can cause deformation or changes in shape. Stress can be caused by various factors such as tension, compression, or shear forces, and it is an important concept in physics and engineering to understand how materials respond to external loads.

6.
It is a material that is used in construction only in conjuction with mortar
Correct Answer brick
Explanation Brick is a material commonly used in construction, particularly in the building of walls and structures. It is made from clay or a mixture of clay and other materials, which is then fired in a kiln to harden it. Bricks are typically used in conjunction with mortar, a paste-like substance made from cement, sand, and water, to hold them together and create a solid structure. The mortar is applied between the bricks, acting as a binding agent to provide strength and stability to the construction. Therefore, bricks are used in construction only in conjunction with mortar.

Span is
A.
In roof framing, horizontal timber connecting two opposite rafters at their lower ends to prevent them from spreading; also: collar beam
B.
The interval between two terminals of a construction / The distance apart of any two consecutive supports, esp. as applied to the opening of an arch. / A structural member (or part of a member between two supports)
Correct Answer
B. The interval between two terminals of a construction / The distance apart of any two consecutive supports, esp. as applied to the opening of an arch. / A structural member (or part of a member between two supports)
Explanation The correct answer explains that "span" refers to the interval between two terminals of a construction or the distance apart of any two consecutive supports, particularly in relation to the opening of an arch. It also mentions that "span" can be a structural member or part of a member between two supports. This definition highlights the various contexts in which "span" is used in construction and emphasizes its role in supporting and connecting different elements of a structure.

Concrete is
A.
Weak in compression and strong in tension
B.
Strong in tension and compression
C.
Strong in compression and weak in tension
Correct Answer
C. Strong in compression and weak in tension
Explanation Concrete is strong in compression and weak in tension because of its composition. Concrete is made up of aggregates (such as sand and gravel) mixed with cement and water. The aggregates provide strength and stability, while the cement acts as a binder. When subjected to compression forces, such as the weight of a building or structure, concrete can withstand a significant amount of pressure. However, when subjected to tension forces, such as stretching or pulling, concrete is more prone to cracking and breaking. This is why reinforcing materials, such as steel bars, are often used in concrete structures to provide additional tensile strength.

9.
Reinforced concrete was developed in order to add ___________ strength to concrete
Correct Answer tensile
Explanation Reinforced concrete was developed in order to add tensile strength to concrete. Tensile strength refers to the ability of a material to resist stretching or pulling forces. Concrete is a strong material in compression but weak in tension. By adding reinforcement, such as steel bars or mesh, to the concrete, its tensile strength is greatly increased. This allows the concrete to withstand bending, stretching, and other tensile forces without cracking or failing.

concrete - shell construction means
A.
A shell construction made of concrete
B.
A contruction in the form of a shell made of concrete
C.
Both a and b
Correct Answer
C. Both a and b
Explanation The correct answer is "both a and b". This means that a concrete shell construction can refer to both a shell construction made of concrete and a construction in the form of a shell made of concrete. In other words, the term "concrete - shell construction" encompasses both of these possibilities.

This picture illustrates a
A.
Slab
B.
Mesh
C.
Ribbing
Correct Answer
B. Mesh
Explanation The correct answer is "mesh" because the picture shows a grid-like structure made up of interconnected wires or bars. This is commonly known as a mesh, which is used in various applications such as reinforcing concrete, creating fences, or providing support in industrial settings. The image does not depict a slab or ribbing, as those terms typically refer to different structural elements or features.

Practice makes you ________
Correct Answer perfect, Perfect
Explanation The proverb "Practice makes you perfect" emphasizes that consistent effort and repetition lead to mastery. Through repeated actions and learning from mistakes, individuals refine their skills, enhance performance, and achieve excellence. The key is dedicated and focused practice, which cultivates proficiency and brings one closer to attaining perfection in a particular skill or task.
