Problem Solving
What is the first question engineers will ask when constructing affordable solar cells?
What is the most cost-effective design process?
What is one constraint the students designing a gravity racing car could face?
Constraints might include size, weight, or materials allowed.
Why is research the first task students should do when redesigning cars for a race?
Research helps understand how to improve designs based on previous experiences.
What is one reason an engineer might build a solar car?
To meet society’s need for a low-cost vehicle that reduces fossil fuel use
What is a trade-off when using a very expensive new material for airplane wings?
It might improve performance, but increase costs.
When engineers research ship design, what will they likely do after deciding on new criteria and constraints?
Reframe the criteria and constraints to match the additional research
In designing an airplane, what is one possible constraint someone could face?
Material availability, cost, or safety regulations.
How does research help engineers in the design process?
It provides an overview of the problem, identifies previous solutions, and defines criteria and constraints.
Why would an airplane need to carry 1,500 to 3,000 people?
To accommodate larger numbers of passengers for long-distance flights.
Why might Charlia choose a more expensive material for her airplane design?
The material might be stronger or more durable, improving safety.
Which step should an engineer complete first when building a new measurement tool?
Precisely define the problem that is to be solved
Name two possible criteria for a shoebox glider.
It should fly a certain distance, and it should be lightweight.
What step should engineers take first before designing a solar car model?
Variable answers.
What are engineers trying to solve when they improve the design of wind turbines?
Concerns about noise and visual impact, as well as efficiency improvements (ETC).
What could be a trade-off when using a more environmentally friendly material in a car design?
It could be more expensive or harder to produce.
If the problem engineers were trying to solve changes after research, what should they do?
Reframe the question, redefine criteria and constraints, and do more research
List two possible constraints for a shoebox glider design.
The glider must use the shoebox as part of the design, and it must meet safety requirements (etc).
What benefit does research provide when designing a solar car?
Research helps identify and define the problem, criteria, and constraints.
Which teacher at CMSLSJ was cheer captain for their high school team?
Ms. D
How might engineers improve an existing material in an airplane design?
By modifying its properties to make it lighter or stronger.
