Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the mechanical principle?Transmission of tensile forces via a rigid structural element
2. What is the key engineering benefit?Ensures direct force transfer and maintains alignment for stability and control
3. What is a drawbar?A drawbar is a strong, rigid piece that connects a hauling vehicle to the thing it pulls, like a truck to a trailer. It pushes or pulls the load straight along the same line, keeping the vehicle and load lined up. This helps the driver steer and keep the load stable.
4. How does a drawbar help trucks and trains?In trucks and trains, a drawbar lets the driver move many trailers or carriages together. It keeps the whole train or road train moving as one long vehicle, so the driver can control it more easily.

Tensile Force: A pulling force exerted by a string, cable, or similar object on a body.
Articulation: The ability of a connection to move or bend at a joint.
Vector: A quantity having direction as well as magnitude, such as force or velocity.
