DETAILED ANSWERS (VERIFIED ANSWERS) |AGRADE
After a company has finished making 5,000 plastic parts, it notices that some of them
are lighter than the first ones that are made. What should be done to solve this
problem? - ANSWER: check the temperature
If the product does not meet the established criteria during production, issues
related to its: - ANSWER: 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
Mr Anderson has decided to ride the Amtrak train from North Carolina to
Washington, DC. He orders his 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
Using the information below, determine the approximate amount of global carbon
emissions as of the year 2000. - ANSWER: 6,750 million metric tons
A new major highway is being planned to connect two small towns. Many of the
townspeople want the highway but have major concerns, as it would pass directly
through a historical area. The townspeople's concerns are an example of how
technology has affected: - ANSWER: Culture
