Presentation on theme: "Index Card Chair Engineering"— Presentation transcript:
1 Index Card Chair Engineering Ignore the paper clips in this photoBuild a chairUse index cardsSupport at least one can20 minutes to build and testBuild an index card chair that can support the weight of an apple, orange or unopened can of soda.
2 Index Card Chair Engineering Engineering CriteriaMust resemble a chair or a chair with an attached footstoolBe able to pick up the chair as one pieceSupport the weight of at least one canEngineering ConstraintsUse only index cardsNo tape, glue, staples, etc.Free standing -- not attached to anything for supportDiscuss difference between qualitative and quantitative criteria.Likewise for constraints.
3 Discussion QuestionsWhen you were given the challenge, what did you do or think?What different designs did you see and which ones were the most effective? Why?How many designs did you try to build before you got one that could support the weight?Did you brainstorm different solutions? Did that help you make a decision as to what would be the best chair to build?Would it have helped to have other tools to build your chair?What would happen if the chair failed?
