universal system
reverse engineering
fatigue test.
troubleshooting.
When testing electric motors, students discovered that when the input power increased, the speed of the motor shafts increased. Which graphical representation would best enable the students to systematically examine this relationship?
Bar chart
Line graph
Pie chart
Scatter plot
Engineers developed a product that is too large to build and to test a prototype. In order to save its budget (moneys), the team must conduct _____ in order to collect data and to determine the product's quality and performance.
a mock-up.
reverse engineering.
computer-based simulation.
tensile test.
The productivity of a design may be established by testing a:

working drawing.
mock-up.
conceptual model.
When looking at the front view of a visual object in an orthographic drawing, the missing dimension from the view would be the:
thickness.
width.
depth.
height.
Which step of the engineering design process would use a graph to communicate the results?
Defining a problem
Exploring possibilities
Making a prototype
Evaluating the design
What is the best choice for communicating information about the design process used to develop a plan for a new mass transit system?
A three-dimensional model of a bus that runs on ethanol
Drawings of different mass-transit routes
A list of ideas about mass-transit problems
A flowchart showing steps developing the plan
Tim is experimenting with different size bowling balls. He notices that even though he throws the different balls at the same speed, that the larger balls tend to cause the pins to move farther and faster when hit. The larger bowling balls have more of what type of energy?
Mechanical
Radiant
Chemical
Electrical
Which energy resource is considered renewable?
Solar
Oil
Natural Gas
Uranium
When atoms are split, they release a lot of thermal energy. The reaction must be controlled, or a reactor can overheat causing a meltdown. A reactor meltdown is a concern related to what type of energy?
Nuclear energy
Radiant energy
Mechanical energy
Electrical energy
Which material is commonly used for nuclear energy?
Coal
Uranium
Petroleum
Solar
In a nuclear fission reaction, what is considered to be the process?
The uranium atoms
The electricity
Homes and business
The splitting of the atoms
If fission means to split an atom, then _ means to combine atoms.
Uranium
Phosphate
Fussion
Zinc
Many of today's largest aircraft carriers use heavy atoms as fuel, and the atoms are split in a fission reactor. This reaction generates heat that is used to produce steam. The steam then spins a turbine and thus the propeller. Which statement explains the progression of energy through this system?
Nuclear to thermal to mechanical
Chemical to thermal to nuclear
Nuclear to radiant to chemical
Chemical to nuclear to mechanical
A hydroelectric dam uses flowing water to spin a turbine which in turn spins a generator which produces electricity. The input of the hydroelectric dam is the mechanical energy in the flowing water. What type of energy is the output of the dam?
Electrical
Radiant
Chemical
Nuclear
