Construction Test 2

Question 1

The _______ is a vertical element that runs through the center of a shutter frame.

Accepted Answer

Mullion

Answer

A mullion is a vertical structural element that divides adjacent window or door units, or in this case, sections within a shutter frame. It provides support and separates the panels or glazing. A reveal is the side of an opening, a style is a vertical member forming part of a frame, and a post is a general term for a vertical support, but mullion specifically describes this dividing element in a frame.

Question 2

_______ refers to the lower half of the arch between the crown and skew back.

Accepted Answer

Haunch

Answer

The haunch of an arch refers to the lower portion of the arch, specifically the section located between the springing line (where the arch begins to curve upwards from its supports) and the crown (the highest point of the arch). This area is crucial for the arch's structural integrity, as it transfers the load to the abutments. Springing is the starting point, soffit is the underside, and spandril is the triangular space above the haunch.

Question 3

The ________ could cause an arch to collapse.

Accepted Answer

All of the options are correct

Answer

An arch can collapse due to several factors, making 'All of the options are correct' the right answer. Crushing of the material occurs if the compressive stress exceeds the arch's material strength. Uneven settlement of the abutments (the supports at the ends of the arch) can introduce differential forces, leading to instability. Lastly, moving voussoirs (the wedge-shaped stones or bricks forming the arch) indicate a loss of interlock or excessive movement, compromising the arch's structural integrity.

Question 4

_______ refers to the outside angle between a wall's outer faces.

Accepted Answer

Quion

Answer

A quoin (pronounced 'coin') refers to the external angle or corner of a wall or building. In masonry construction, quoins are often distinguished by being built of larger, dressed stones or bricks, or by being laid in a different pattern, to provide both structural strength and aesthetic emphasis to the corner.

Question 5

In general, a flight of stairs shouldn't have fewer than _____ steps.

Accepted Answer

3

Answer

In general, a flight of stairs should not have fewer than three steps. This minimum number helps to clearly define a change in level, making the stairs more discernible and safer to use. Having too few steps can create a tripping hazard, as people may not perceive the elevation change adequately.
