Truss Quiz

What is a truss?

• A network of beams arranged in squares

• A network of beams arranged in circles

• A network of beams arranged in triangles

• A single long beam used for support

What basic form provides a truss with strength?

• Rectangles

• Triangles

• Circles

• Hexagons

How can a spanning truss be reduced in mass while maintaining strength?

• By adding more beams to the truss

• By replacing beams with string

• By making the beams thicker

• By using heavier materials

What is the advantage of using trusses in construction?

• They allow for different structural designs.

• They reduce the strength of triangles.

• They are only used for roofs of houses.

• They distribute weight only at the ends of the structure.

What do trusses take advantage of to make structures strong?

• The strength of rectangles

• The strength of circles

• The strength of triangles

• The strength of hexagons

Why are arches used in construction?

• To support the weight of the structure above them

• To make structures look more aesthetically pleasing

• To reduce the cost of construction materials

• To increase the tension force in a structure

How do arches transfer force?

• Upward from keystone to the base

• Sideways from one end to the other

• Downward from each stone to the next

• In a circular motion around the arch

Which early civilization is known for using arches in building structures?

• The Greeks

• The Egyptians

• The Romans

• The Mayans

What is the purpose of the keystone in an arch?

• It is purely decorative.

• It supports the entire weight of the arch.

• It transfers tension force to the base.

• It locks the other stones in place and bears the most pressure.

What is a dome in the context of structures?

• A. A support structure that uses a network of triangles to distribute weight

• B. A structure that looks like the top half of a sphere or an egg

• C. A horizontal beam supported at its ends

• D. A vertical column that primarily resists compressive stress
