MPa ni ksi ga qanday aylantiraman?

1 ksi = 6.89476 MPa. To convert MPa to ksi: divide by 6.89476. Example: 500 MPa = 72.5 ksi.

MPa va N/mm² o'rtasidagi farq nima?

They are identical. 1 MPa = 1 N/mm² = 1 MN/m². Both are commonly used in engineering for stress and strength values.

Kuchlanishni kuchga qanday o'tkazish mumkin?

Force = Stress × Area (F = σ × A). For example, 500 MPa stress on a 100 mm² cross-section: F = 500 × 100 = 50,000 N = 50 kN.

kgf/mm² nima va u qachon qo'llaniladi?

Kvadrat millimetrga kilogram-kuch. Ba'zi rus, yapon va eski evropa standartlarida hali ham qo'llaniladigan eski metrik birlik. 1 kgf/mm² = 9,80665 MPa.

Po'latning tipik mustahkamlik qiymatlari qanday?

S235: Rp=235 MPa, Rm=360 MPa. S355: Rp=355 MPa, Rm=510 MPa. AISI 4140 Q&T: Rp=655 MPa, Rm=900 MPa. Stainless 304: Rp=210 MPa, Rm=520 MPa.

Kuchlanishdan Kuchga

Amaliy Misol

Misol — S355 oqish kuchlanishini o'zgartirish

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.
