Question

Define tensile strain​

Answer 1

tensile strength is is a property of fibre or metal which allow a metal or fibre to bear a lot of strength without breaking it

Answer 2

Answer:

Explanation:

Definition -

Tensile stress is the resistance of an object to a force tending to tear it apart.

It is calculated as the highest tension the object can endure without tearing, and is measured in Newtons/sq.mm, but was initially denoted as tons/sq. in.

Stress is defined as the force per unit area of a material:

Stress = Force / Cross sectional area

and is a measurement of the strength of a material. Therefore, tensile stress refers to a force that attempts to pull apart or stretch a material.

Many of the mechanical properties of a material can be determined from a tensile test. In a tensile test, a sample is strained at a constant rate and the stress needed to maintain this strain rate is measured.

A tensile test can determine:

• Elastic modulus
• Ultimate tensile stress
• Fracture stress
• Modulus of toughness
• Modulus of resilience

Tensile stress is also known as normal stress or tension.
