This Week in Technology

This week in tech we reviewed the forces of flight. The first day we went out to test fly paper airplanes.  Made a modified dart, which was just a heavier nose (see image below). My airplane went relatively far. The next day we learned about the 4 forces of flight, and I learned about gliders. Gliders are made to be lightweight and to glide without an engine or thrust. They rely on manipulating the air flow to stay up in the air. The next few days we worked on orthographic drawings, or blueprints. I drew an orthographic  drawing of a warehouse, and learned how to use guiding lines to draw the blueprint.



Aluminum Foil Physical Properties.

Aluminum foil has many physical properties. For example, it has a ductility of around 300 MPa, so it is not very ductile. On the other hand it is very malleable and can be formed into many things. Like a tin foil ball or being shaped around food or other items. It does no fare well under tensile strength, or stretching, but it can withstand high amounts of compressive strength. In fact, aluminum foil, is basically a sheet of aluminum under compressive strength to make it thin and malleable. In addition to malleability it is also formable, meaning it can be formed or molded around and shaped into different forms.
