MAE 1351 COMPREHENSIVE EXAM STUDY
GUIDE WITH COMPLETE SOLUTIONS
●● center-of-mass (centroid):
Answer: The origin of the
coordinate axes for which the first moments are zero.
●● constraint
Answer: A boundary condition applied to a
finite element model to prevent it from moving
through space.
●● density
Answer: The mass per unit volume for a given material.
●● displacement:
Answer: A change in the location of points on
an object after it has been subjected to external loads
●● Finite Element Analysis
Answer: An advanced computer based
design analysis technique that involves subdividing
, an object into several small elements to determine
stresses, displacements, pressure fields, thermal distributions,
or electromagnetic fields.
●● mechanical stress
Answer: Developed force applied per unit
area that tries to deform an object.
●● mesh
Answer: The series of elements and nodal points on a
finite element model.
●● moment-of-inertia
Answer: The measure of an object's ability
to resist rotational acceleration about an axis
●● radius-of-gyration
Answer: The distance from an axis where
all of the mass can be concentrated and still produce the
same moment-of-inertia.
●● reverse engineering
