Desi gn P ro c ess a nd the E ngi neeri ng No teb o o k Use the engineering design process Document the steps in your engineering notebook 7

Desi gn P ro c ess Do c um enta ti o n This will be quick Focus on the process Refer to the Activity Sheet as you Go 8

E ngi neeri ng No teb o o k: Ti tl e Title Should be Short As more pages are needed you will use this same title when working on this project Page Number 9

E ngi neeri ng No teb o o k: Define the P ro b l em Defining the Problem Should Only Take About 1 Minute Simple Problem Statement: No Details 10

E ngi neeri ng No teb o o k: Co nstra i nts Constraints (1 minutes) Constrains should be listed with values and units 2 linking Cubes (3/4 in) 11x 8.5 inch Paper 11

E ngi neeri ng No teb o o k Prior Solution Attempts (2 minutes) Research any past designs Document 3 sources (could be websites) In future more time could be given but today 2 minutes 12

E ngi neeri ng No teb o o k: Brainstorm (2 Minutes) Generate and communicate as many concepts as possible Take the full 2 minutes but make sure you have atleast 3 sketches 13

E ngi neeri ng No teb o o k Develop A Solution (2 Minutes) This could mean Building This could me annotating a sketch 14

E ngi neeri ng No teb o o k Construct and Test Prototype (10 Minutes) This is the time when you act Take your developed solution and move it into prototype phase Test 15

E ngi neeri ng No teb o o k Evaluate a Solution (1 Minute) What went right What can you improve on 16

E ngi neeri ng No teb o o k Present Solution Tend to keep this to an Elevator Pitch (2-3 minutes) 17

W ha t i s desi gn Design is turning a concept into a product that can be produced. Design is a process that you follow to solve problems. 19

Statics, does it matter? 20

Statics, does it matter? Or is a C good enough? 21

At work one day you are sitting at your desk and the boss comes in and says: You know the TV tower you designed? The site called said they have a small problem. Could you to go down there and see what the problem is. When you arrive you see .

I knew I shouldnt have slept in Exploration Class!

3 persons died in this accident. It was caused by an incorrect calculation of a simple Statics problem!

At work one day you are sitting at your desk and the boss comes in and says: You know the electrical transmission towers you designed? The northeast US has lost power and they think there might be something wrong with your towers. Could you go down there and see what the problem is. When you arrive you see .

Oh, here is that missing negative sign!

Two-level catwalk failed under live load, causing fatalities. Original design called for nuts where they could not actually be installed: original (impossible) design had each nut only helping to support the weight of one floor; the rod passing through the upper floor also passed the load of the lower floor through it, and not the nut holding up the upper floor. The installed design meant the nut under the upper floor not only had to support the weight of the upper floor but also the weight of the lower floor; the nut and rod were undersized to handle this load.. Upper catwalk supported itself and lower catwalk, by means of rods offset from one another. Live load may have caused harmonic oscillation by dancing. Even the static load of people exceeded design. Nuts tore through overloaded members. Blame and liability for failure were "spread around," but some licenses were still lost.
