MAE 1351 EXAM 2 (A+ GRADED)

Element sizes should be correct answers reduced wherever there is curvature in the model to compute desired quantities accurately in those regions the overall moment-of-inertia. correct answers 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 correct answers static This measure command returns the area of a specified surface and the length of the perimeter surrounding that surface correct answers Measure surface this measure command returns the center and radius of an arc correct answers Measure Arc This measure command returns the shortest (perpendicular) distance between a line and another identified entity, such as a point: correct answers 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. correct answers 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 correct answers insert; concentric Instances correct answers the copies of a component within the system subassembly correct answers 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 correct answers associativity heirarchy correct answers The organization or structure of a system ________ remains stationary with the other instances moving into place around it correct answers Base instance clearances correct answers minimum distances between parts Interference correct answers The amount that two instances overlap ______________ may need to be known to increase a device's stability correct answers center-of-mass FEA stands for correct answers Finite Element Analysis
