In Figure 2.16, the weight of the upper piston (W) is 85 pounds (39 kg) and has a surface area of 113 in² (729 cm³). The weight (W) of the lower piston is 14 pounds (6 kgl and has a surface area of 12.6 in (81 cm). If the liquid in the hydraulic system is an oil with a specific gravity of 0.90, what force (F) will be required to attain a state of equilibrium? Figure 2.16 Illustration for Exercise 2.12.
