boundary conditions - Correct Answer The constraints and loads
added to the boundaries of a finite element model.
center-of-mass (centroid): - Correct Answer The origin of the
coordinate axes for which the first moments are zero.
constraint - Correct Answer A boundary condition applie...
mechanical stress - Correct Answer Developed force applied per unit
area that tries to deform an object.
mesh - Correct Answer The series of elements and nodal points on a
finite element model.
, moment-of-inertia - Correct Answer The measure of an object's ability
to resist rotational acceleration about an axis
radius-of-gyration - Correct Answer The distance from an axis where
all of the mass can be concentrated and still produce the
same moment-of-inertia.
reverse engineering - Correct 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? - Correct 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? - Correct Answer IT IS A
MEASURE OF THE BODY'S PROPERTY TO RESIST CHANGE IN ITS
STEADY ROTATION ABOUT THE AXIS. IT DEPENDS ON THE
BODY'S MASS AND ITS DISTRIBUTION AROUND THE AXIS
Is it easier to spin a
wheel with a large diameter or a small diameter? - Correct Answer a wheel with a large diameter will be
harder to accelerate
to a desired rotation rate than a wheel with a small diameter. so its easier to spin a wheel with a small
diameter
What are constraints in an FEA? - Correct Answer A way to hold the object (model) simulating
attachment. it is also a way to let the analysis know that part is fixed
What kinds of boundary conditions can be applied
to a finite element model? - Correct Answer stress analysis - forces or defined displacements
