A car is put into a garage higher by a hydraulic lift. How large should be the surface on which the vehicle rest if you to lift a vehicle of 1000kg higher with overpressure of 1 atm?
Homework Equations
[/B]
Pabsolue pressure = P atmos + P relative
P=F/A
F=m xa
The Attempt at a Solution
P absolute = 101325 Pa +101325 pa
1000kg x9.81 m/s^2 / (A) = 202650
1000kg x 9.81 =202650A
A= 1000x9.81 /202650
A=0.04840 m^2
But the answer should be 9,682.10-2 m 2
