A tension-force replaces what objects when creating a Free Body Diagram?
A.) None of these
B.) Sprocket
C.) Chain
D.) Cable
E.) Rope

Option C D and E

chains cables and ropes.

Explanation:

A free body diagram is a simple sketch showing the forces acting on objects in a physical system.

Usually tensile forces  are those forces that occur on objects that are pulled by a force. To get the correct answer choices we need to identify the objects that are most likely to be pulled by a force in any physical system. Such objects from our options include: chains cables and ropes.

This means that whenever these are acting in a physical system, they are mostly used in tension.

Consequently, whenever a free body diagram of such system is drawn, chains cables and ropes.are usually replaced by tension force arrows
