nameless Posted May 10, 2019 Share Posted May 10, 2019 Where did I go wrong? Pascal is kg .metre ² . m sec². Why is it 1.019.. and not 1? Why is MPa not 100kg F cm² ? "1 megapascal [MPa] = 10.1971621297793 kilogram-force/centimeter²" If .5kg at 40msec² strikes on 1cm² is that 80 or 8MPa? Link to comment Share on other sites More sharing options...
nameless Posted May 10, 2019 Author Share Posted May 10, 2019 OK gram force 9.80665 the speed of gravity inverse. But it still needs G squared for gravity equations so where's the benefit? Still don't get the 10 /100 of cm² =metre². Link to comment Share on other sites More sharing options...
Sensei Posted May 10, 2019 Share Posted May 10, 2019 Your way of expressing is very confusing. It's not really clear what actually you want. 1 Pa = 1 Pascal 1 Pa = 1 N/m^2 = [math]\frac{N}{m^2} = \frac{kg}{m*s^2}[/math] 101970 Pa = 101970 [math]\frac{N}{m^2}[/math] = 10.197 [math]\frac{N}{cm^2}[/math] 1 m = 100 cm therefor 1 m^2 = 100 * 100 cm^2 = 10,000 cm^2 Link to comment Share on other sites More sharing options...

nameless Posted May 10, 2019 Author Share Posted May 10, 2019 OK then 1 million pascals is 100kg/ cm 2. Megapascal is approximately that - was there a need to make it different? It tricked me up. Link to comment Share on other sites More sharing options...

The fact that the acceleration due to gravity at the Earth's surface (9.80665 m/s/s) is near, but not exactly, 10 m/s/s is down to whoever designed the Earth.

nameless Posted May 10, 2019 Author Share Posted May 10, 2019 aha , but it's not squared in gram force . That's human intervention due to pressure from Satan. Link to comment Share on other sites More sharing options...

Would you like to try that again, but with more rational explanation and less dross? Link to comment Share on other sites More sharing options...
nameless Posted May 10, 2019 Author Share Posted May 10, 2019 1 million pascals is rational . The gravity figure in Megapascal is not , it's diabolical and is not given as a2. . MPa has a lot of explaining to do. Link to comment Share on other sites More sharing options...
