Understanding Arch Components

The video tutorial provides an in-depth explanation of the various parts of an arch and their functions. It lists and defines 17 key terms related to arch construction, such as the striking point, abutments, span, springing point, and more. Each term is explained with its role in the structure of an arch, offering a comprehensive understanding of arch terminology and architecture.

What is the striking point in an arch?

• The highest point of the arch

• The center point of the circle of which the curve of the arch is a part

• The lowest point where the curve begins

• The distance between the abutments

Which part of the arch is supported by the abutments?

• The key brick

• The springing line

• The span

• The striking point

What is the springing line in an arch?

• A vertical line through the center of the arch

• A horizontal line drawn between the two springing points

• The line that marks the highest point of the arch

• The line that separates the intrados and extrados

Which brick is placed last in the construction of an arch?

• The Creeper

What is the extrados of an arch?

• The inner or bottom curve of the arch

• The external or top curve of the arch

• The highest point on the arch

What is the function of the skewback in an arch?

• It is the external or top curve of the arch

• It is the highest point on the extrados

What are creepers in the context of arch construction?

• The central brick in the arch face
