MAE 1351 Exam 1 Questions With
Correct Answers 2024/2025
descriptive geometry - Correct Answer A 2D graphical construction technique used for
geometric analysis of 3D objects
Optimization - Correct Answer 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? - Correct Answer 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? - Correct Answer Walls became thicker,
and more geometrically complex to deflect cannon fire
Why did engineering drawings need to become more precise during the industrial
revolution? - Correct Answer reduced misinterpretation so products could be mass
produced
What were the three traditional roles of engineering graphics? - Correct Answer
communication, record keeping, and analysis
What are some of the new roles of engineering graphics created by computer graphics?
- Correct Answer (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? - Correct Answer
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? - Correct Answer 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 - Correct Answer false

- Correct Answer true
, To create a solid of revolution, I must... - Correct Answer select a plain line from the
sketch to use as a an axis, make an axis in the sketch using a construction line, use
reference geometry to make an axis
These are the fundamental types of sketch constraints: - Correct Answer geometrical
and dimensional
I have a distance in my sketch preceded by a "sigma" symbol. This means... - Correct
Answer it is a dimension driven by a parametric formula
To create the "wedge" homework, this is the best choice of technique: - Correct Answer
well it depends...
The following feature facilitates removal from a mold - Correct Answer draft
I need to add a clearance hole to my part for fastening. Which is better from a design
intent perspective? - Correct Answer hole made with a hole wizard
A blend (loft) requires at least these many profile sketches: - Correct Answer two
COTS stands for: - Correct Answer Comercial Off The Shelf

Bulk formation includes - Correct Answer casting, modeling, powder metallurgy, rapid
prototyping
Bulk deformation includes - Correct Answer forming (forge, roll, extrude, vacuume) and
sheet metal (drawing, stamping, bending)
Material removal includes - Correct Answer sawing, drilling, turning, milling, grinding,
die cutting, sheet metal (punching), EDM
joining includes - Correct Answer welding, soldering, bonding, fastening, ultrasonic,
brazing
finishing includes - Correct Answer polishing, painting, plating, aniodizing, heat treat
One of the limitations of sawing as a fabrication process is... - Correct Answer can not
perform circular cuts
