Aerospace Engineering EOC Exam
Questions And Answers 2025 Update
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 - Answer✔Design Process
is a device incorporating a calibrated screw widely used for accurate measurement of
components in mechanical engineering and machining as well as most mechanical trades -
Answer✔Micrometers
Use is comparable to the vernier calipers, however, the gradations are not as precise. It's
measuring capacity is up to 3 inches. - Answer✔Slide Calipers
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. - Answer✔Isometric drawing
A drawing that is used to show the material, size, and shape of a product for manufacturing
purposes. - Answer✔technical drawing
a set of working drawings used in engineering that depict complete details of all components. -
Answer✔assembly drawings
a type of drawing shown in three dimensions; includes isometric, oblique, and perspective
drawings. - Answer✔pictorial drawing
a drawing that has several views used to describe the object. It is also called a multiview
drawing. - Answer✔orthographic 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 - Answer✔schematic drawing
- dimensions are read horizontally
- dimensions are centered on the dimension line

- tends to use abbreviations
- different syntax (1.000 DIAM 3 PLACES)
- drawings typically use Third Angle Projections with dimensions in inch units - Answer✔ANSI
measurements
- 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)
- different syntax (3X Ø 1.000)
- drawings typically use First Angle Projections for view placement with dimensions in
millimeter units - Answer✔ISO measurments
Compression, tension, torque, and Shear - Answer✔Types of stress
A force that pushes on or squeezes a material.
(arrows pointing towards each other) - Answer✔compression
stress that occurs when forces act to stretch an object
(arrows pointing away from each other) - Answer✔tension
a turning or twisting force - Answer✔torque
force directed parallel to a surface - Answer✔shear
relates change in stress to the deformation it produces - Answer✔Stress-Strain Curve
ultimate strength
(σ⨍ on diagram) - Answer✔point A on Stress-Strain Curve
yield point
(σy on diagram) - Answer✔point B on Stress-Strain Curve
yield point
(ɛy on diagram) - Answer✔point C on Stress-Strain Curve
necking begins, begins due to the increase of local stress on an object which accelerates the
flow of energy. Necking makes the deformation occur only in a specified area of the specimen
compared to the uniform deformations that occurred throughout the specimen before necking
occurred.
(basically what happens with a fracture so that's what the picture is (: ) - Answer✔What
happens on a microscopic level on the ultimate strength point of a stress- strain curve?
