Question

what unit of ultimate tensile strength​

Answer 1

Answer:

psi

Tensile strengths have dimensions of force per unit area and in the English system of measurement are commonly expressed in units of pounds per square inch, often abbreviated to psi

Answer 2

${\huge{\sf{\green{\underline {\underline {Answer }}}}}}$

⇒Ultimate tensile strength (or just tensile strength for short) is an important property of materials to determine their mechanical performance. It is the ability of a material to resist tearing due to tension. This parameter applies to all types of materials such as wires, ropes, metal beams, etc

What Is Tensile Strength?

⇒Imagine a strip of paper being pulled at its two ends with your fingers. You are applying a tensile force on the strip. When this tensile force crosses a certain threshold, the paper tears. The tensile stress at which this takes place is the tensile strength of that material, in this case paper.

⇒When excessive tension is applied, both ductile, as well as brittle materials will approach a point of failure. Initially there will be a uniform deformation observed. All throughout the body of the material, its length will increase while its width reduces at the same rate.

⇒Ultimate tensile strength is the amount of stress that pushes materials from the state of uniform plastic deformation to local concentrated deformation. The necking phenomenon begins at this point.
