Which term defines a large structural element used to resist bending and support loads in bridges?

• A. Nose Cone
• B. Load
• C. Girder
• D. Investigation

Answer: (C)

In bridges, the large horizontal element that carries the weight and resists bending is called a girder. Girders are the main load-bearing members that span between supports (such as abutments or piers) and transfer the deck’s loads down to those supports. They’re designed to withstand bending moments from traffic, gravity, and environmental effects, often taking shapes like steel I-beams or box girders that provide high stiffness and strength. The other terms don’t relate to a structural bridge component: a nose cone belongs to rockets, a load is the force acting on structures, and an investigation is a process. So the term that best defines the component resisting bending and supporting loads in bridges is girder.
