Question

What is the primary force that helps suspension bridges use cables to hold their spans up? A. tension force B. resistance force C. normal force D. elastic force E. applied force

Answer 1

Answer:

The correct answer is option A. "tension force".

Explanation:

Suspension bridges, like the Golden Gate Bridge or the Brooklyn Bridge, use tension force as the primary source of force that cables use to hold their spans up. The supporting cables receive the tension forces of the bridge, and this same force passes to the anchorages and into the ground. This equilibrium that the tension force gives among the different elements of the bridge, gives the support to hold the bridge together.

Answer 2

Answer:

A. Tension force

Explanation:

These are bridges that use cables to hold the road way up.

The cables in a suspension bridge receive the tension force of the bridge. These cables transmit these forces to the towers supporting the bridge and are compressed into the ground.
