MAE 1351 EXAM 1 2026 MULTICHOICE ANSWERED EXAM
QUESTIONS WITH DETAILED RATIONALES
1.
A completed 2D sketch that is later used in a CAD system to generate a 3D solid feature is best
described as which of the following?
A. Construction geometry
B. Datum plane
�C. Profile
D. Reference axis
Rationale: A profile is a closed sketch used to create solid features such as extrusions or
revolutions.
2.
When two curves or surfaces touch at exactly one point without crossing each other, the
geometric relationship is called:
A. Coincident
�B. Tangent
C. Concentric
D. Collinear
Rationale: Tangent entities touch at one point without intersecting.
3.
Constraints that control size, shape, orientation, and include assumptions made by the CAD
system are known as:
A. Explicit constraints
�B. Implicit constraints
C. Dimensional overrides
D. Cosmetic constraints
Rationale: Implicit constraints are automatically applied and hidden from the sketcher.
,ESTUDYR
4.
Which constraint forces two points to occupy the exact same location in a sketch?
�A. Coincident
B. Parallel
C. Tangent
D. Equal
Rationale: Coincident constraints merge two points into one location.
5.
Which constraint forces the centers of two circles or arcs to align?
A. Coincident
�B. Concentric
C. Collinear
D. Tangent
Rationale: Concentric constraints align circle centers.
6.
Forcing one line to lie directly along the same infinite line as another requires which constraint?
A. Parallel
�B. Collinear
C. Coincident
D. Tangent
Rationale: Collinear ensures lines lie on the same line.
7.
Constraints that define distances between two points or lines are known as:
A. Angular constraints
�B. Linear constraints
, ESTUDYR
C. Radial constraints
D. Associative constraints
Rationale: Linear constraints specify straight-line distances.
8.
Which constraint specifies the radius or diameter of a circular entity?
A. Linear
B. Angular
�C. Radial
D. Algebraic
Rationale: Radial constraints define circular size.
9.
Constraints that measure the angle formed between two lines are classified as:
�A. Angular constraints
B. Linear constraints
C. Radial constraints
D. Variational constraints
Rationale: Angular constraints control angular relationships.
10.
Constraints that link one dimension mathematically to another using equations are called:
A. Implicit constraints
�B. Associative constraints
C. Linear constraints
D. Ground constraints
Rationale: Associative (algebraic) constraints relate dimensions via equations.
