Descriptive geometry - ACCURATE ANSWERS✔✔ A 2D graphical
construction technique used for geometric analysis of 3D objects
Optimization - ACCURATE ANSWERS✔✔ Modification of shapes,
sizes, and other variables to achieve the best performance based on
predefined criteria
Why are most cave drawings and hieroglyphics not considered to be
engineering drawings? - ACCURATE ANSWERS✔✔ Becuase they
were mostly documentation of lifestyle, not instructions on how to build
something
In what ways did the design of military fortifications change after the
discovery of gunpowder and the invention of the cannon? - ACCURATE
ANSWERS✔✔ Walls became thicker, and more geometrically complex
to deflect cannon fire
Why did engineering drawings need to become more precise during the
industrial revolution? - ACCURATE ANSWERS✔✔ reduced
misinterpretation so products could be mass produced
, What were the three traditional roles of engineering graphics? -
ACCURATE ANSWERS✔✔ communication, record keeping, and
analysis
What are some of the new roles of engineering graphics created by
computer graphics? - ACCURATE ANSWERS✔✔ (visualization,
analysis, function, and optimization) can produce 3D pictures that can be
observed from all sides, can be tested on the computer vs having to test
actual models
What are some of the advantages and disadvantages of using mechanical
drawing instruments, as opposed to mathematical tools, for problem
solving? - ACCURATE ANSWERS✔✔ Mechanical drawing
instruments were used to analyze problems without the need to do
burdensome math and enabled engineers to create any view of a
geometric object from two existing views
In what ways can visualization skills be developed? - ACCURATE
ANSWERS✔✔ by doing special visualization exercises, by building
and working with solid models, disassembling and reassembling
devices, and sketching
T/F The engineering design process follows the same steps as the
scientific discovery process, or scientific method - ACCURATE
ANSWERS✔✔ false
T/F To create a revolved feature, the profile and the axis of revolution
must be coplanar. - ACCURATE ANSWERS✔✔ true
