4. Why do engineers use special fasteners in airplanes?Airplane fasteners are made from special alloys that can handle very hot or very cold temperatures and keep parts from moving when the plane vibrates.

Torque: A measure of the twisting force applied when tightening a fastener.
Tensile Strength: The maximum stress a material can withstand before breaking when pulled.
Fatigue: The weakening of a material caused by repeatedly applied loads.
