Try looking at sensor manufacturers and construction documents for more real-life examples. MPa 10000 psi Water pressure withstood by the DSV Shinkai 6500 in visiting ocean depths of > 6500 meters: 70 to 20 to 40000 psi. The news media is rife with speculation that engineering flaws caused the collapses.įor more information on practical uses of MPa and pressure scales, several engineering publications and industry guides are available. Recent high profile bridge collapses in Florida and Genoa, Italy put engineering documents into the spotlight. Correct calculation of objects under load is critical to safety. 8,000 psi (55,2 MPa) > 6,500 psi (44,8 MPa) > 6,000 psi (41,4 MPa). Concrete used in warehouses, factories, and other large-scale commercial properties often requires 4,000-5,000 PSI. Concrete in this range is also a good choice for concrete slabs for storing RVs or other heavy loads. Applications In EngineeringĬonstruction and tank manufacturers use MPa or ksi to communicate tensile strength for platforms or tanks. Structural components like beams and footers require a PSI of 3,500-4,000. The resin used for your back teeth must be rated to withstand 6 MPa, or about 900 psi. The dental crown of your back molar needs to withstand much, much more. How To Calculate Pound-force Per Square Inchs To Megapascals. The second part of the figure shows an inclined plane aa cut through the same point in the material but oriented at an angle. MPa 6160 - 6500 psi Average 44 MPa Grade Count 3 Elongation at Break 23. Your chipped front tooth needs to withstand the pressure of 1 MPa, or about 145 psi. Problem 7.2-13 At a point on the surface of a machine the material is in biaxial stress with x 3600 psi and y 1600 psi, as shown in the first part of the figure. Applications In Healthĭentists and medical professionals use MPa to communicate tensile strength of cured resins for tooth and bone repair. ![]() ![]() Hydraulic systems, such as lifts, airplane controls, and brakes often use MPa to communicate pressure and tensile strength values.įor example, the pressure in a steam locomotive is around 1 MPa, a pressure washer generates around 10 MPa, 25 MPa is a typical diesel brakes system.Ĥ00 MPa is the chamber pressure inside a machine gun.
