Building Technology Quiz Questions

Control joints are joints that are intentionally created in masonry walls to allow for movement and reduce restraint. These joints are designed to accommodate the expansion and contraction of the masonry due to temperature changes and other factors. By providing controlled points of separation, control joints help to prevent cracking and damage to the masonry walls. Cold joints, on the other hand, refer to joints that are unintentionally created due to a delay in the placement of concrete or masonry. Block out joints are not specific to reducing restraint in masonry walls.

The statement is true because the horizontal distance from the face of a lock or latch to the center of the knob is indeed called a backset. The backset measurement is important for determining the compatibility of a lock or latch with a door, as it ensures that the knob or lever can be properly installed and function correctly.

A pantile is a type of roofing tile that has the shape of an "S" laid on its side. It is a curved tile that is commonly used in Mediterranean and Spanish-style architecture. The shape of the pantile allows for efficient water drainage and provides a visually appealing pattern when installed on a roof.

Balloon framing is a system of framing a building where the studs run continuously from the foundation to the roof, supporting the second-floor joints. This method became popular in the mid-19th century and was commonly used in North America. It allowed for faster and more efficient construction compared to traditional post and beam or western framing methods. The continuous studs provide structural stability and allow for the construction of taller buildings.

A foundation wall is the correct answer because it refers to the part of the building foundation that serves as a permanent retaining wall below grade. This wall provides support and stability to the structure, preventing soil erosion and maintaining the integrity of the foundation. It is typically made of concrete or masonry and is designed to withstand the pressure exerted by the surrounding soil.

Wrought iron is a commercially pure iron that is known for its fibrous nature and corrosion resistance. It is valued for its strength and durability, making it suitable for various applications such as gates, fences, and decorative items. Unlike cast iron, which is brittle and prone to breakage, wrought iron can be easily shaped and forged into different forms. Its fibrous structure gives it a unique appearance and texture, adding to its aesthetic appeal. Therefore, the correct answer for the given question is wrought iron.

A principal member of the truss which extends from one end to the other primarily to resist bending is a chord. Chords are horizontal or inclined members that provide stability and support to the truss structure. They are typically located at the top and bottom of the truss and are responsible for resisting the bending forces that act on the truss. Chords play a crucial role in maintaining the structural integrity of the truss and ensuring its stability under various loads and conditions.

The correct answer is tyrolean finish. A tyrolean finish is achieved by flinging plaster onto a wall using a hand-operated machine. This technique creates a rough and textured surface, which is commonly used for exterior walls to provide both decorative and protective properties. The plaster is applied in a way that creates a patterned effect, giving the wall a unique and visually appealing finish.
