Linear Equations
• Y=mx+b form
• Can be used to predict linear data
![Page 18: Jesse Smith Industrial Engineering](https://reader036.fdocuments.in/reader036/viewer/2022062720/568134af550346895d9bc9a6/html5/thumbnails/18.jpg)
Quadratic Equations
• y = ax2 + bx +c form
• Used as one way to graph data in a non linear form

This is clearly not a linear function. A quadratic model might be used to predict the optimal wing length. Before going to an optimal measurement a ROBUST design based on a linear model might be used
![Page 25: Jesse Smith Industrial Engineering](https://reader036.fdocuments.in/reader036/viewer/2022062720/568134af550346895d9bc9a6/html5/thumbnails/25.jpg)
Robust Design
Sometimes the optimal is not the best. If a design falls within the acceptable operating parameters and is more efficient to produce, then it might be more economically feasible to use this design.
1 hour to produce 2 minutes to produce
Which one would you choose ?

Siege weapons and their usesIn Medieval warfare it was sometimes necessary to lay siege to an enemy fortification. e.g. a castle.

Several Devices were developed to help deal with these situations.
The other was the trebuchet.
One of these was the ballista.

By knowing the height of the target and the distance tables could be developed slope and
angles could be compared.
