Group: The captain should email everyone to make sure they have a job pushing your project forward. Email your wishlist to email@example.com. Work on the website – there should be the company name, mission statement and pictures/explanations of your first (and possibly second) prototype.
Use as much of the weekend as you can addressing your Individual Challenge. You will need most of your class energy next week for your group project. If you need programs for laser-cutting, you can download Illustrator and use the free trial (https://creative.adobe.com/products/illustrator). If you want to use the 3-D printer, use thingiverse.com and augment the object on Sketch-Up (remember to get the free version: http://www.sketchup.com/download)
Damocles picture “quiz” – have you been asking questions of each other, TAs and Triggs? Start collaborating!
ropes: 1/4 inch yellow polypropylene rope with a tensile strength of 5.5kN
boulder: 1 ton with a diameter of 1 foot and 8 inches
length of ropes: (can be determined using proportionality. Use the picture and remember that the diameter of the boulder is 1 foot and 8 inches)
The person, knots and wire can hold 10,000 pounds
The person can bench press twice his body weight (wow!)
Distance between person and boulder (can be determined using proportionality. Use the picture and remember that the diameter of the boulder is 1 foot and 8 inches)
The downward force of the weight: Weight is the force due to gravity. Since the gravitational force (weight) is between the rock and the earth, the force the rock experiences is towards the earth. The short answer is 1 ton (convert to Newtons, perhaps?)
A neat video to the digits of Pi. How many digits do you know?
Group: Whoever takes the prototype home should do user testing. Record (video, audio, written reflection) your experience. Everyone in the group records ways that the prototype works well, needs improvement, and any questions you have.
Decide what Individual Challenge you will take on and draft a paragraph proposal of what you want to do in your notebook.
From the Damocles picture “quiz”, make a model, also known as a free body diagram (imagine just the front view of a technical model) in your notebook.
Is Damocles Safe?
Below is the story of the Damocles and a model of his dire situation. Use your understanding of statics to ask for questions/quantities that will help you estimate whether or not Damocles is safe. Put your questions in the comments. Answers are due the last day of class in your notebooks.
Choose one of the following previous activities to develop for your individual challenge
- Gift Giving – choose a person for whom you want to thank. Interview them to see what they might want/need. Brainstorm ideas that might fit that need. Create an object that you think would work. Test it with your person (or someone who knows your person well). Make another version of the gift to present to the person for which you want to recognize.
- Build a device that improves your waking up experience based on your classwork. Try it out on yourself and take note of what worked, what needs improvement, questions you now have and ideas. Make a new device that meets your needs.
- Fix or change an object so that it meets your needs.
- Based on the feedback about your computer game, make a new version. Do user-tests on your new version and take notes about what worked, what needs improvement, questions you now have and ideas. Make another version of your game.
- Create an art piece that will remind/inspire people to change their behavior for the better. Use at least two of the following: 3-D printing, laser-cutting, micro-controllers, electronics, wood or metal.
- What’s your idea?
Each student will have to make their resume
