QUESTIONS
Actual Qs and Ans - Expert-Verified Explanation -Guaranteed passing score -61 Questions and Answers
-Format: Multiple-choice / Flashcard
Question 1: force
Answer:
What has a magnitude(strength) that you can measure, and it has a direction?
Question 2: Compression
Answer:
____ is a force that pushes materials together.
- Air pressure and Water pressure
Question 3: Emptying Tanks equation
Answer:
Converting inflow rate (gallons per minute):
gal/sec x 60
Subtract: gal/min inflow
Question 4: Atmospheric pressure
Answer:
14.7 lb/in²
Question 5: Pistons
Answer:
Goes up and down and returns to its original position.
Question 6: Cranks
Answer:
Used to change motion in a straight line to motion in a circle.
Question 7: To find amount of water pressure equation
Answer:
Total weight of water ÷ by area of base
Question 8: Potential energy
Answer:
Energy that can be released under certain conditions.
Question 9: Forces
Answer:
_____ are powers that push or pull objects.
Question 10: Fluids
Answer:
Substance that take the shape of their container.
Question 11: Structural Support
Answer:
- Load of any kind is supported by two support beams, posts, or person the load is perfectly balanced if
its exactly centered (bearing exactly half of load). If it isn't centered the beam, posts, or person nearer to the load has the most weight.
Question 12: Simple Machines
Answer:
Group of very common basic devices such as the lever, Pulley, inclined plane, gear, wedge, and wheel and axle, and the screw.
Question 13: Effort arm (effort distance)
Answer:
The part of the lever from the force to fulcrum.
Question 14: Friction
Answer:
a force that results from the interaction between two surfaces that are touching each other.
- can act as air resistance
- acts as a resistance to the movement of an object.
Question 15: Gas Laws
Answer:
Air as it is compressed and expanded
- Gas compressed = gains thermal energy(warms up), gains potential energy (ex: compressed air is
- Given the amount of gas expands = pressure drops and the gas cools
- Gas cools without a change in outside pressure = loss volume
used for nail guns and pneumatic hammers)
Question 16: Chemical energy
Answer:
Energy stored in chemicals. (flashlight batter)
Question 17: Electric energy
Answer:
Energy in moving electrons in an electric current.
Question 18: Solar energy
Answer:
Energy in the heat and light from the sun.
Question 19: Steel reinforcing
Answer:
It is placed at the bottom of a bridge, where its tensile strength can support the load.
Question 20: Refrigerators
Answer:
A compressor compresses a fluid, called a refrigerant
- warms up). It loses heat (but not pressure) in the condenser (placed in an area where it gets rid of
excess heat).Refrigerant is piped into an evaporator (found in areas where is cooled.), it goes through a small hole and evaporates under reduced pressure.The expansion causes the temperature to drop, and cold refrigerants can pick up heat from the surroundings.
Question 21: Nuclear energy
Answer:
Energy released by reactions in the nucleus of an atom.
Question 22: Fulcrum
Answer:
Stationary element that holds the lever but still allows it to rotate.
Question 23: Effort
Answer:
The force applied to lift or squeeze.
Question 24: Levers
Answer:
A device that helps you apply force to lift a heavy object.-Fulcrum Load Load Arm Effort Effort Arm
Question 25: Speed of Pulley
Answer:
Speed 1 x diameter 1 = Speed 2 x diameter2
