Answer: 349.99 Newton must be exerted on the small piston

Step-by-step explanation:

In changing a tire a hydraulic jack lift 7468 newtons on its large piston which has an area of 28.27 cm squared. Pressure is expressed as force/area

Pressure exerted and transmitted to the smaller piston is

7468/28.27 = 264.14N/cm²

If the small piston has an area of 1.325 cm squared, the force that would be exerted on the smaller piston is

Force = pressure × area

= 264.14 × 1.325 = 349.99 Newton
