Stress to Force
Practical Example
Given: Rp0.2 = 355 MPa
= 355 N/mm² = 0.355 GPa = 355,000 kPa
= 355 / 6.895 = 51.5 ksi = 51,488 PSI
= 355 / 9.807 = 36.2 kgf/mm²
= 355 × 10 = 3,550 bar
Force on 200 mm² bar: F = 355 × 200 = 71,000 N = 71.0 kN

💡 Tip: 1 MPa = 1 N/mm² exactly. This is the most common unit for mechanical properties in international standards. In the US, ksi (= 1000 PSI) is standard.

Nikolai Shelkovenko
Nikolai Shelkovenko is a vibration analysis engineer and the founder and CEO of Vibromera. For more than 15 years he has balanced rotating equipment in the field rather than on a test bench: mulchers, industrial fans, crushers, centrifuges, shafts and spindles. That work is what the Balanset instruments grew out of — they were designed as a tool a specialist can carry to the machine and use alone, on site, not as laboratory equipment. Vibromera was founded in 2017 and has been based in Porto, Portugal, since 2023. Development, assembly and support of the Balanset line all happen here. The flagship instrument is the Balanset-1A, a portable analyser for single- and two-plane balancing and for vibration diagnostics. Nikolai is personally involved in customer support, in working through difficult balancing cases and in the development of the software. He works with customers worldwide, in any language.
