What must you remember to check when dealing with the units of given quantities for cylinder size in calculations involving force and pressure?
The units will always be in meters
The units will be squared if given the area
The units will be in kilograms
The units do not matter
If you are given the diameter or radius in a problem involving the calculation of pressure, what must you do?
Calculate the circumference of a circle
Calculate the volume of a cylinder
Calculate the area of a circle
Ignore the diameter or radius as it is not important
What is pressure considered to be when calculating fluid power?
A property of an individual cylinder
A type of force
A property of the system
A measurement of area
What is the value of π (pi) used in the calculation of the area of a circle?
π = 3
π = 3.2
π = 3.14
π = 2.718
What is the formula to calculate pressure?
Pressure = force + area
Pressure = force / area
Pressure = force x area
Pressure = area / force
If a force of 250 lbf is applied to a cylinder with a diameter of 6 inches, what is the area of the cylinder's face (in square inches) that the force is applied to?
12.36 in2
113.04 in2
28.26 in2
18.84 in2
What is the pressure applied to the cylinder if a force of 250 lbf is applied to an area of 50 in2?
4.973 lbf/square inch
5 lbf/square inch
10 lbf/square inch
20 lbf/square inch
What is the output force experienced by an area when it is exposed to a constant pressure?
It remains constant regardless of the area size.
It decreases as the area size increases.
It increases as the area size increases.
It is not related to the area size.
Based on the principle of force multiplication, what would be the output force if a 100 lbf input force is applied to a 2 in² area, which is then transmitted through a fluid to a 12 in² area?
50 lbf
200 lbf
600 lbf
1200 lbf
When calculating the efficiency of a real system, what should you expect as your answer?
Equal to 100%
Higher than 100%
Lower than 100%
The motor running a certain pump draws power of 150 KW of electricity. The output of the pump in fluid power is 135 KW. What is the efficiency of the pump?
81.67%
75%
90%
111%
What is the definition of a fluid in fluid power?
Any liquid
Any gas
Any solid
Any liquid or gas
What does it mean if a fluid is incompressible?
The volume does not change with pressure
If you add a force to one side of the system, there is a delay in the transmission across the system
The volume changes with pressure
All fluid power systems are incompressible
What does pneumatic mean?
Power is transferred to do work through a liquid
A motor creates rotational power
A pump creates fluid power
Power is transferred to do work through a gas
What does hydraulic mean?
Power is transferred to do work through a liquid
A motor creates rotational power
A pump creates fluid power
Power is transferred to do work through a gas
