The unit, named after Blaise Pascal, is an SI coherent derived unit defined as one newton per square metre (N/m 2). [1] It is also equivalent to 10 barye (10 Ba) in the CGS system. Common multiple units of the pascal are the hectopascal (1 hPa = 100 Pa), which is equal to one millibar , and the kilopascal (1 kPa = 1000 Pa), which is equal to ...
The ultimate tensile strength of a material is an intensive property; therefore its value does not depend on the size of the test specimen.However, depending on the material, it may be dependent on other factors, such as the preparation of the specimen, the presence or otherwise of surface defects, and the temperature of the test environment and material.

A bolt with property class 12.9 has a tensile strength of 1200 MPa (1 MPa = 1 N/mm 2) or 1.2 kN/mm 2 and the yield strength is 0.90 times tensile strength, 1080 MPa in this case. A bolt with property class 4.6 has a tensile strength of 400 MPa (1 MPa = 1 N/mm 2 ) or 0.4 kN/mm 2 and yield strength is 0.60 times tensile strength, 240 MPa in this ...

The statohm is a unit of electric resistance equal to 1 statV/statA, corresponding to ~ 898.755 1787 GΩ. The statsiemens or statmho is a unit of electric conductance equal to 1 statA/statV, corresponding to ~ 1.112 646 pS. [6] The stathenry is a unit of electric inductance equal to 1 statV·s/statA, corresponding to ~ 898.755 1787 GH. [7] [6] [a]
The specific strength is bounded to be no greater than c 2 ≈ 9 × 10 13 kN⋅m/kg, where c is the speed of light. This limit is achieved by electric and magnetic field lines, QCD flux tubes , and the fundamental strings hypothesized by string theory .
Compressive strength is measured on materials, components, [1] and structures. [2] The ultimate compressive strength of a material is the maximum uniaxial compressive stress that it can withstand before complete failure. This value is typically determined through a compressive test conducted using a universal testing machine. During the test, a ...
