boundary conditions - The constraints and loads

added to the boundaries of a finite element model.



center-of-mass (centroid): - The origin of the

coordinate axes for which the first moments are zero.



constraint - A boundary condition applied to a

finite element model to prevent it from moving

through space.



density - The mass per unit volume for a given material.



displacement: - A change in the location of points on

an object after it has been subjected to external loads



Finite Element Analysis - 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 - Developed force applied per unit

area that tries to deform an object.



mesh - The series of elements and nodal points on a

finite element model.

, moment-of-inertia - The measure of an object's ability

to resist rotational acceleration about an axis



radius-of-gyration - The distance from an axis where

all of the mass can be concentrated and still produce the

same moment-of-inertia.



reverse engineering - : 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? - 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? - 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? - 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? - 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
