Final answer:
The top and the bottom of an I-shaped beam are called the flanges. They provide support and help distribute the weight and forces acting on the beam, allowing it to resist bending and other structural loads.
Step-by-step explanation:
The top and the bottom of an I-shaped beam are called the flanges.
The flanges are the horizontal plates that make up the top and bottom of the I-shaped beam.
They provide support and help distribute the weight and forces acting on the beam, allowing it to resist bending and other structural loads.
