MPA calculation VS MPA listed on materials

AI Thread Summary
The discussion centers on the confusion surrounding the calculation of MPA (Mega Pascal) from tensile strength values. The original poster calculated an MPA of .0035163 from a tensile strength of .51 PSI, leading to confusion when comparing this to much higher MPA values listed for materials like glass. Participants clarified that MPA is a unit of pressure and emphasized the importance of proper unit conversion. The conversation highlights the significant difference between PSI and MPA, illustrating that .51 PSI is a very low pressure. Understanding these units is crucial for accurately selecting materials based on their strength properties.

Hi,

I am not a mathematician or scientist or student. In advance I ask that you please excuse my ignorance. I calculated that at tensile strength of .51 equals an MPA of .0035163. Thank god for internet calculators. I do not know what MPA means, but materials are listed this way. So if I want to choose a material with an MPA of greater than .0035163 and I look at the MPA of materials, the MPA listed seems mammoth in comparison and defies logic. For example, glass is listed as having an MPA of 60. So what am I missing?

Sorry - .51 PSI

Yeah, but did you get DEvans answer of what MPA means (to be accurate, it should be written as MPa)? You never indicated if by that information, you realize that this is a psi to MPa unit conversion.

Zz.
 
Oh. For 0.51 PSI you don't need much of a container. You could probably get that much pressure from a party balloon.
 
comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
