Explanation Of The Engineering Design Process:
To do the engineering design process you need to do it by steps. There are eight steps to doing
the process and you need to do them very slow and carefully so you do not mess up. First, you need to
identify the problem. Second , Research the problem for information on the problem. Third, Develop
possible solutions. Fourth, you need to select the best possible solution. Fifth, you need to construct a
prototype. Sixth, test and evaluate the solution. Seventh, communicate the solution. Finally, you need to
redesign the prototype.
I used the engineering design process for my car. My car did not work but when i used the
design process I took my time and went through every step in order. I first took notes about how to
make the car. Then, I made the prototype which came out better than my actual car. After, I made
changes by making the wheels CD’s and the structure of my car a different quality. It did not turn out
better then my first prototype. Infact, My final car did not even move.
My purpose of making a prototype for my car is to test materials out. If I just made the final car
and then winded it up and it did not work then I would not do so good on the car. The point of a
prototype is that you can test the before car how it can work and what will slow it or make it faster. The
five elements of the universal system model is Goal, Input, Output, Process and Feedback. These five
elements are used to help you understand what you are doing when you make the car. The change from
Potential energy and Kinetic energy is how you can calculate the speed of an objects decent. The
subsystems in my car that I made was the propulsion, the whole structure of the car, and guidance. The

propulsion is the elastic that when you twist it, it will move the car. The guidance is the wheels, and they
are what makes the car move. The structure is the whole car ingerneral. The structure holds everything
together, without it the car would not move.
