- 150 feet
- 140 feet
- 130 feet
- 120 feet
- Answer

3. Metal workers are most likely to use a press brake for which of the following purposes?
- welding
- forging
- bending
- grinding
- Answer

Energy and Power Systems
Objective 0005
Understand fluid systems and their role in technology systems.
4. Use the diagram below to answer the question that follows.
a positive displacement compressor, with the longer edge of the unit on the x-axis. Two ports extend up and out of the top, one near the far left of the top edge and the other the far right. Within the unit there is a shaded rectangular block drawing of the piston with three segments. A narrow vertical piece is near the far left port and is the same height as the unit it is inside, attached at the center, a narrow horizontal piece extends out to the right through the right edge of the compressor unit where a third rectangular segment is attached and is a shorter, wider rectangular block.
In this positive displacement compressor, the advantage of having two ports rather than one is that:
- pressure in the cylinder can be monitored.
- gas can enter the cylinder at a faster rate.
- power can be provided in both directions.
- exhaust gases can leave the cylinder.
- Answer
- Correct Response: C.
Correct Response: C.
Objective 0006
Understand thermal systems and their role in technology systems.
5. A hand-cranked generator has an efficiency of 75%. A person supplies 300 J of energy to turn the generator which is used to power an electric motor. If the motor has an efficiency of 80%, what is the output of the motor?
- 15 J
- 180 J
- 225 J
- 240 J
- Answer
- Correct Response: B.
Correct Response: B.

6. In residential construction, an important difference between balloon framing and platform framing is that in balloon framing:
- the building rests on a full-height foundation.
- the studs extend from the foundation to the top plate.
- the upper stories rest entirely on the joists of lower stories.
- the roof consists of pre-assembled rafters.
- Answer
