What happens to a structural member when it is subjected to compression?

• It elongates

• It shortens

• It bends

• It twists

What is a beam in structural engineering?

• A vertical element that supports horizontal loads.

• A structural element that carries a load that is applied transverse (perpendicular) to its length.

• A flexible element that bends without carrying any loads.

• A decorative element in architecture that does not carry loads.

What happens to the bottom fibers of a beam under a vertical load?

• The bottom fibers are in compression.

• The bottom fibers are in shear.

• The bottom fibers are in tension.

• The bottom fibers remain neutral without any stress.
