Academic Discourse Community Rhetorical Analysis - Essay Example and they are promising three alternative choice design packages, each comprising â€Å"of a multi-faceted approach to slow precipitation runoff and enhance soil infiltration†. They have included the imminent challenges they predict and the appropriate design budget. The proposal outlines the entire project execution framework including a Gantt schedule and appendices defining the team profile and other miscellaneous project details. Massachusetts Institute of Technology (MIT). â€Å"New ultrastiff, ultralight material developed†. ScienceDaily, ScienceDaily. 19 July 2014. Web. 15 July 2014. A group of researchers have applied the construction model of the Eiffel tower to create extremely light and stiff materials. The Eiffel tower achieves its strength from its geometric model. Researchers have managed top microscale this concept using 3-D printing in a process called projection microstereolithography. Normally stiffness and strength reduce as density reduces, but these researchers are claiming that by employing the â€Å"right mathematical ly determined structures to direct and distribute the load† light structures can maintain their strength. The researchers tested aerogel (glass foam) and found that its mechanical strength compared with that of solid rubber and increased by 400times while compared to objects of similar density. This means that this sample can support 160000 its weight. They have achieved similar results in other tests involving metal, ceramic and polymer. This development is useful for installations requiring light and strong materials like space structures. They can also be used for sound and elasticity solutions because they conduct sound.
