Trusses work because the individual members __________.

• A. Are stronger than one large beam
• B. Link and reallocate the loads of tension and compression evenly in a structure
• C. Are in a particular pattern unique to trusses
• D. Can withstand compression

Answer: (B)

Trusses work by forming a network of straight members arranged in triangles so loads can be shared and transferred efficiently. When a load hits the structure, it travels from joint to joint along the members, with some members in tension (being pulled) and others in compression (being pushed). The triangular arrangement and connections let these forces be redistributed through many paths to the supports, so no single member has to carry the entire load. This distribution of tension and compression throughout the network is what gives a truss its strength and efficiency. It's not about one member being stronger than a solid beam, nor about a unique pattern being required, and it doesn't rely on all members just resisting compression.
