A car has a mass of 1200 kg. A man can comfortably push down with a force of 400 N. If the small piston in a hydraulic jack has
kotegsom [21]
A) F1/A1=F2/A2
F2 = 12000 Newtons, while F1 = 400 Newtons and area A1= 6 cm²
400/6 = 12000/A2
A2 = (6 × 12000)/400
     =  180 cm²
 
b) How long does this lift the car
 d2 =F1/F2×d1
      = (400/12000)× 20
       = (1/30)×20
       = 20/30
       = 0.67 cm
This lifts the car a distance of 0.67 cm
