Engineering Design Process
What is the first step in the engineering design process?
Define the Problem
This non-renewable energy source is a major source of propulsion for different vehicles like cars and aircraft.
Petroleum/Oil
A ramp is an example of this simple machine.
Inclined Plane
A keyboard is an example of this in the Universal Systems Model.
Input
This force is generated by many things such as helicopter rotor blades.
Lift
Differing proposals are given to solve the problem, this is an example of what step?
Brainstorming
This non-renewable resource is known for starting the industrial revolution's surge in production.
Coal
Lever
This step in the Universal Systems Model is the way in which a product is made.
Process
Aircraft engines and rocket motors generate this force.
Thrust
What two things must be defined before a product is designed and constructed?
Criteria and Constraints
An element of this energy source used in production is Uranium.
Nuclear
This is the point at which a lever is supported to lift loads.
Fulcrum
Light that comes from a bulb is an example of this.
Output.
Stress balls are commonly made to be squeezed. Squeezing an object is an example of this force.
Compression
When feedback is received you go to this step of the Engineering Design Process.
Refine the Design
This energy source accounts for less that 3% of all total energy output and relies on the heat from the Earth.
Geothermal
Mill stones were one of the first common uses of this simple machine.
Wheel and Axle
This is the last step in the Universal Systems Model and is key to product improvement.
Feedback
This is the force which is generated when, for example, the rope of a pulley is pulled to lift a load.
Tension
This is a first generation pre-production solution to the problem. It may have some problems that need to be ironed out. The first attempt.
Prototype
This is the junction at which the two main layers of a solar panel meet.
P-N Junction
This simple machine uses an incline plane in a helical shape surrounding a central rod.
Screw
The Global Positioning System (GPS) is an example of which of the steps of the Universal Systems Model.
Output
The rotation around a certain point is the force called what?
Torque
