MPA calculation VS MPA listed on materials

Click For 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.
 
I'm not a student or graduate in Astrophysics.. Wish i were though... I was playing with distances between planets... I found that Mars, Ceres, Jupiter and Saturn have somthing in common... They are in a kind of ratio with another.. They all got a difference about 1,84 to 1,88x the distance from the previous planet, sub-planet. On average 1,845x. I thought this can be coincidential. So i took the big moons of Jupiter and Saturn to do the same thing jupiter; Io, Europa and Ganymede have a...
