Which of the following is true about the hydraulic system?
The pressure exerted on a smaller piston is greater than on the larger piston.
The pressure exerted on a larger piston is greater than on the smaller piston
The pressure exerted on a small piston is equal to that on the larger piston
The pressure applied to the fluid causes the volume of fluid to increase
Diagram above shows a brake system of a car. Which principle is used in this system?
Pascal's principle
Bernoulli's principle
Archimedes' principle
Principle of conservation of momentum
Diagram above shows a hydraulic pump. Which of the following statement is true?
The force F is the same as the weight of the load.
The force F is greater than the weight of the load
The pressure on piston P is the same as the pressure on piston Q
The pressure on piston P is smaller than the pressure on piston Q.
Diagram above shows a simple hydraulic system in equilibrium. A1, A2 and A3 are the areas of the piston. F1, F2 and F3 are the forces which act on the piston.
Pressure at A1= Pressure at A2= Pressure at A3
Pressure at A1 < Pressure at A2 < Pressure at A3
Pressure at A1 > Pressure at A2 > Pressure at A3
Pressure at A1 > Pressure at A2 = Pressure at A3

A
B
C
D
Diagram above shows a Bernoulli tube. The pressure at tube X, Y and Z is given as Px, Py and Pz. Which of the following is the correct comparison?
Px = Py = Pz
Px > Py > Pz
Px < Py < Pz
Py > Px > Pz
Diagram above shows a helicopter moving in the air. What produces the lifting force?
