Question

The important parameter which is considered for the measure of ductility is:

• A. Ultimate tensile strength
• B. Yield strength
• C. Percentage of elongation
• D. Modulus of toughness

Hint:

Ductility is most commonly measured by the percentage of elongation during a tensile test.

Answer 1

The Correct Option is C

1. Ductility:
Ductility is the ability of a material to undergo significant plastic deformation before fracture. It is an important property for materials that need to stretch or deform without breaking. 2. Measurement of Ductility:
The most common parameter used to measure ductility is the percentage of elongation. This is determined by measuring the increase in length of a material specimen when subjected to a tensile test, and then calculating the percentage increase in length compared to the original length. 3. Why Not Other Options:
Ultimate tensile strength (Option 1) refers to the maximum stress a material can withstand without breaking, but it does not directly measure ductility.
Yield strength (Option 2) is the stress at which a material starts to deform plastically, but it is not a direct measure of ductility.
Modulus of toughness (Option 4) refers to the total energy a material can absorb before failure, but again, it doesn't directly measure ductility.
