In a beam bridge, what force is experienced at the top of the beam?

• Torsion

• Compression

• Shear

• Tension

What happens to a beam bridge when a load is applied?

• It remains unchanged

• It expands

• It bends and experiences tension and compression

• It contracts

What was the load capacity of the longer beam bridge in the experiment?

• 25 pounds

How does an arch bridge distribute load?

• Evenly through the arch into the ground

• Through tension forces

• By bending the deck

• By using cables

Why are arch bridges suitable for wood and stone materials?

• They are stronger in compression

• They are more flexible

• They are stronger in tension

• They are lighter

What is a limitation of arch bridges?
