MAE 1351 Exam 2 (Engineering Graphics (SolidWorks) at UTA): Updated Solution

Hierarchy (ans- the parent-child relationships between instances in an assembly. Base instance (ans- the one fixed instance within an assembly. Assembly constraints (ans- used to establish relationships between instances in the development of a flexible assembly model. Components (ans- references of object geometry use in assembly models Instances (ans- copies of components that are included within an assembly model. Subassembly (ans- a logical grouping of assembly instances that is treated as a single entity within the overall assembly model. Associativity (ans- the situation where by parts can be modified and the components referenced to the parts will be modified accordingly. Exploded configuration (ans- a configuration of an assembly that shows instances separated from one another. An exploded configuration is used as the basis for an assembly drawing. Interference (ans- the amount of overlap between two instances in an assembly. Clearances (ans- the minimum distances between two instances in an assembly. Bill of materials (ans- a tabular list of the components, with quantities of each for the parts, that make up an assembly. Center-of-mass (ans- the origin of the coordinate axes for which the first moments are zero. Radii-of-gyration (ans- the distance from an axis where all of the mass can be concentrated and still produce the same moment-of-inertia. Moments-of-inertia (ans- the measure of an object's ability to resist rotational acceleration about an axis.
