  2. Pound per square inch - Wikipedia

    en.wikipedia.org/wiki/Pound_per_square_inch

    The kilopound per square inch (ksi) is a scaled unit derived from psi, equivalent to a thousand psi (1000 lbf/in 2). ksi are not widely used for gas pressures. They are mostly used in materials science, where the tensile strength of a material is measured as a large number of psi. [4] The conversion in SI units is 1 ksi = 6.895 MPa, or 1 MPa ...

  3. Ultimate tensile strength - Wikipedia

    en.wikipedia.org/wiki/Ultimate_tensile_strength

    In the International System of Units (SI), the unit is the pascal (Pa) (or a multiple thereof, often megapascals (MPa), using the SI prefix mega); or, equivalently to pascals, newtons per square metre (N/m 2). A United States customary unit is pounds per square inch (lb/in 2 or psi). Kilopounds per square inch (ksi, or sometimes kpsi) is equal ...

    In Imperial units, the unit of stress is given as lbf/in 2 or pounds-force per square inch. This unit is often abbreviated as psi. One thousand psi is abbreviated ksi. A factor of safety is a design criteria that an engineered component or structure must achieve.

  9. Breaker bar - Wikipedia

    en.wikipedia.org/wiki/Breaker_bar

    Chromium vanadium steel has a yield strength at 0.2% offset of 84.0 kilo-pound per square inch (KSI). Meaning, chromium-vanadium steel can withstand up to 84 KSI before it begins to yield. [7] If the steel is unloaded before the yield point it is elastic and the material will return to its original configuration.
