QUESTIONS AND ANSWERS
Element sizes should be - ANS reduced wherever there is curvature in the model to compute
desired quantities accurately in those regions
the overall moment-of-inertia. - ANS is claculated by summing up all the moments-of-inertia;
which are calculated by multiplying the mass of the piece by the distance from the axis
Mass properties are the ________ properties of a solid body - ANS static
This measure command returns the area of a specified surface and the length of the perimeter
surrounding that surface - ANS Measure surface
this measure command returns the center and radius of an arc - ANS Measure Arc
This measure command returns the shortest (perpendicular) distance between a line and
another identified entity, such as a point: - ANS Measure Line Distance
In the case that your software requires assembly models be fully constrained, you are usually
permitted to include __________ with your constraints in order to satisfy the need for system
flexibility and movement. - ANS assumptions
An ___________ constraint is a special type of ___________ contraint used to insert a fastener
such as a bolt into a hole in a different part - ANS insert; concentric

, Instances - ANS the copies of a component within the system
subassembly - ANS a grouping of components that serves a single purpose within the overall
assembly
_____________ means that if you change the geometry of a part, the component and all
instances of it also will change by the same amount - ANS associativity
heirarchy - ANS The organization or structure of a system
________ remains stationary with the other instances moving into place around it -
ANS Base instance
clearances - ANS minimum distances between parts
Interference - ANS The amount that two instances overlap
______________ may need to be known to increase a device's stability - ANS center-of-mass
FEA stands for - ANS Finite Element Analysis
FEA - ANS an advanced design analysis technique that has been made possible through the
development of sophisticated 3-D CAD solid modeling tools
