Question

Difficulty: EasyMaterial Properties

A winch cable made of steel is subjected to heavy pulling forces. The cable can stretch slightly under this tension rather than snapping instantly. Which material property allows the steel to stretch and deform under pulling forces without breaking?

  1. DuctilityAnswer
  2. B
    Brittleness
  3. C
    Compressive strength
  4. D
    Hardness

Answer

Ductility
Ductility is the specific mechanical property that allows a material to be drawn out or stretched under tension without fracturing. This makes it ideal for cables that must handle pulling forces safely.

Step-by-Step Solution

1
Identify the type of force acting on the cable.
The cable is subjected to heavy pulling forces, which is known as tension.
Understanding the force helps determine which material property is relevant.
2
Determine which material property describes stretching under tension.
Ductility is the property that allows a material to deform or stretch under tensile stress without breaking.
Matching the force (tension) and behavior (stretching) to the correct definition isolates the correct property.
