Megapascals

What is the area of crosssection of the piston, if the force of 300 kN produces a pressure of 5 MPa?

Result

S =  600 cm2

Solution:

p=5 106=5000000 F=300 1000=300000 p=F/S S1=F/p=300000/5000000=350=0.06 S=1002 S1=1002 0.06=600=600 cm2p = 5 \cdot \ 10^{ 6 } = 5000000 \ \\ F = 300 \cdot \ 1000 = 300000 \ \\ p = F/S \ \\ S_{ 1 } = F/p = 300000/5000000 = \dfrac{ 3 }{ 50 } = 0.06 \ \\ S = 100^{ 2 } \cdot \ S_{ 1 } = 100^{ 2 } \cdot \ 0.06 = 600 = 600 \ cm^2



Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
