This script computes the load carried by the larger piston in a hydraulic system

Enter the initial force in N: 150
Enter the final force in N: 200
Enter the increment value: 10
Enter the area of small piston in mm^2: 25
Enter the area of big piston in mm^2: 100

F1    F2
150  600
160  640
170  680
180  720
190  760
200  800
