AEROSPACE ENGINEERING EOC QUESTIONS
& ELABORATED COMPLETE SOLUTIONS
1. Design Process a systematic problem-solving strategy, with criteria and
constraints, used to
develop many possible solutions to solve a problem or satisfy
human needs and wants and to winnow (narrow) down the possible
solutions to one final choice
2. Micrometers is a device incorporating a calibrated screw widely used for
accurate mea-
surement of components in mechanical engineering and
machining as well as most mechanical trades
3. Slide Calipers Use is comparable to the vernier calipers, however, the gradations
are not
as precise. It's measuring capacity is up to 3 inches.
4. Isometric drawing The drawing of a 3d object that shows a corner view of a
figure. it is not
drawn in perspective and the distances are not distorted.
5. technical drawing A drawing that is used to show the material, size, and shape of
a product for
manufacturing purposes.
6. assembly drawings a set of working drawings used in engineering that depict
complete details
of all components.
7. pictorial drawing a type of drawing shown in three dimensions; includes
isometric, oblique,
and perspective drawings.
8. orthographic a drawing that has several views used to describe the object. It is
draw-ing also called a multiview drawing.

9. schematic drawing clearly, detailed diagrams of an electrical or mechanical system,
are a
top-level focus drawing and describe how something works and/or
how individual parts interface; often used in a concept or early
design stage to outline a design and its principles
10. ANSI measurements - dimensions are read horizontally
-dimensions are centered on the dimension line

-tends to use abbreviations
-ditterent syntax (1.000 DIAM 3 PLACES)
-drawings typically use Third Angle Projections with dimensions in
inch units
11. ISO measurments - dimensions are parallel to the dimension line
-dimension are placed above the dimension line
-uses symbols. (example: RAD, DIAM, 3 PLACES versus R, Ø, 3X)
-ditterent syntax (3X Ø 1.000)
-drawings typically use First Angle Projections for view
placement with dimensions in millimeter units
12. Types of stress Compression, tension, torque, and Shear
13. compression A force that pushes on or squeezes a material.
(arrows pointing towards each other)
14. tension stress that occurs when forces act to stretch
an object (arrows pointing away from each
other)
15. torque a turning or twisting force
16. shear force directed parallel to a surface
17. Stress-Strain Curve relates change in stress to the deformation it produces
