Regarding the hydraulic jack in Problem 3.18, which ideas were used to analyze the jack? Select all that apply:

a. Pressure = (force)(area)

b. Pressure increases linearly with depth in a fluid with a constant density

c. The pressure at the bottom of the 4-cm chamber is larger than the pressure at the bottom of the 10-cm chamber

d. When a body is stationary, the sum of forces on the body is zero

e. When a body is stationary, the sum of moments on the body is zero

f. Differential pressure = (weight/volume)(change in elevation)

Data from Problem 3.18,

If a 390 N force F₁ is applied to the piston with the 4 cm diameter, what is the magnitude of the force F₂ that can be resisted by the piston with the 10 cm diameter? Neglect the weights of the pistons.
