MAE 1351 FINAL PAPER 2026 COMPLETE
QUESTIONS AND ANSWERS
◉ Instances. Answer: copies of a component w/in a
system(assembly)
◉ An assembly cannot be nested inside an existing assembly; only
parts can.. Answer: False
◉ What are the benefits of an assembly. Answer: - makes it easier to
modify a part and propagate within the assembly
- saves computer memory
◉ Associativity. Answer: if the geometry of a part is changed then
the components and instances of that part will also change by the
same amount.
◉ Parent-Child Relationships. Answer: Associations between
components and subassemblies
Parent-subassembly
Child- component
,◉ base instance. Answer: The instance chosen to orient other
instances in space relative to itself
-they are stationary
◉ What is the difference between Top-Down and Down-Up
Hierarchy. Answer: Top -Down: breaking the assembly down to its
components
Down-Up: Building the assembly from its components to its
assembly final form
◉ What purpose do reference planes serve for an assembly. Answer:
they connect to base component and serve as the coordinate planes
for the space defined by the system
◉ Assembly Constraints. Answer: dimensional and geometric
constraints between 2 3D instances so the instances maintain their
geometric/dimensional relationships w/respect to each other w/in
the assembly.
◉ Degrees of Freedom. Answer: a quantity used to represent the
location and orientation of a part in 3D space
◉ I bring a part into an assembly in SW and click the OK check mark
in the top right. This will.... Answer: Align component origin with
assembly origin
, ◉ I bring a cube into an assembly and mate-coincident one of its
edges to a fixed edge. It now has these many DOFs:. Answer: 2
◉ I bring a cube into an assembly and mate-coincident one of its
vertices to a fixed vertex. It now has these many DOFs:. Answer: 3
◉ For every mate I apply, I reduce the DOF of the part by these
many:. Answer: Depends on the mate
◉ I bring a cylinder into an assembly and mate-parallel one of its flat
faces to the top plane. This causes it to lose these many DOFs:.
Answer: 2
◉ Mechanical Mates. Answer: Applies to mechanisms when there is
a programmatic motion btw 2 components meaning it doesn't
happen naturally from other geometrical constraints
Orientated towards power transmission
◉ Do you want your system fully constrained. Answer: NO because
the assembly will be rigid and unable to move and will revert to its
original orientation to satisfy all of the constraints if you try to move
an instance.
