Quality control must be investigated
A working model used to test a design during development is called a: - Answer-Prototype
The activities that might result in new or improved products and processes describe what activity used
in industry? - Answer-Research and development
When selecting a material for use in a product, each material has advantages and disadvantages. One
must view the qualities of material and make compromises as they design the final product, this product
is known as a: - Answer-Trade-off
Which technological device was a catalyst for additional scientific discoveries? - Answer-Microscope
,Energy is stored in the form of chemical energy. The chemical energy is then converted to electrical
energy to run an electrical motor. The electric motor changes the electrical energy into mechanical
energy. This change is an example of what law? - Answer-First law of thermodynamics
The invention by the U.S. Army of a water filter that is now available public use is an example of: -
Answer-Technology transfer
When an operator notices that a CNC machine is making rough cuts, the most likely cause is that the
cutter: - Answer-Needs to be sharpened
Thomas Edison's invention of the lightbulb has affected every persons day-to-day life. This is an example
of how technology has affected: - Answer-Society
The magnetron in a microwave oven creates microwaves. The microwaves inside the cooking area are
an example of what type of energy? - Answer-Radiant
The process used to make a design or system as effective or efficient as possible is? - Answer-
Optimization
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? - Answer-
Nuclear to thermal to mechanical
When refining a design, which method would yield information to improve the efficiency of the design? -
Answer-Computer stimulations
Which step of the engineering design process would use a graph to communicate the results? - Answer-
Evaluating the design
, If a solar cell can be made that breaks the water into H2 and O2, then the H2 can be stored and run
through a fuel cell to generate electricity. To make this happen will require: - Answer-Research
There are many scientific concepts that are used by engineers and designers. Which concept would not
be included? - Answer-Colors that match green
Soybeans have many uses, from food to fuel and even lubricants. Before the soybeans can be converted
into useful products, they must be: - Answer-Cleaned, dried, and cooled.
As knowledge and skills increase, modification to products advance from one generation to the next.
This is an example of? - Answer-Technological evolution

tickets online and pays with a gift card he received as a parent. When he arrives at the depot, he goes up
to a ticket machine and types in his confirmation number and he is dispensed a train ticket. What type of
communication was mr Anderson engaged in at the train depot. - Answer-Human to machine
The focus group usually consists of groups of 5-7 people that are surveyed. The data collected from the
focus group should be considered: - Answer-Opinion
When a spacecraft reenters the atmosphere, friction causes an intense amount of heat on the outer
skin. What heat resistant material would be good to protect the spacecraft while reentering? - Answer-
Ceramic
The study of technology should look at how the development of new technology affects humans at both
the; - Answer-Local lever and global level
