COMPLETE QUESTIONS AND SOLUTIONS
GRADED A+
● 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. Answer: : A systematic methodology for
analyzing the design of an existing device.
● What are some of the mass properties that can be
computed for a CAD model?. Answer: Density, Mass, Volume, Surface
area, Center-of-mass or centroid, principle aces-of-inertia and principle
moments-of0inertia, radius-of-gyration
● What is a moment-of-inertia?. Answer: IT IS A
