Definitions:

Tensile Strength

A measure of the maximum amount of stress a material can withstand while being stretched or pulled before breaking.

Minimum Yield Strength

The lowest stress at which a material begins to deform permanently, important in material selection for engineering.

Twisting Force

Also known as torque, it's the force that causes an object to rotate about an axis, fulcrum, or pivot.

Tightening Nuts

The process of securing nuts onto bolts or studs to a specified torque, ensuring a stable assembly.
