MAE 1351 EXAM 1, MAE 1351 Exam 2 combined 160 Questions with Correct Answers The engineering design process follows the same steps as the scientific discovery process, or scientific method. True? -... Answer- No; there are major differences The term "IPS" in SolidWorks refers to... -Answer- measurement units To create an extrusion, I must first draw a sketch on a surface. True? -Answer- Yes, but the surface must be flat What are the fundamental types of sketch constraints? -Answer- Geometrical and dimensional To clock a hexagonal feature so that it rests horizontally on one side, I would... -Answer- Apply a horizontal constraint To create a revolved feature, the profile and the axis of the revolution must be what? -Answer- Coplanar To create a solid of revolution, I must... A) Select a plain line from the sketch to use as an axis B) Make an axis in the sketch using a construction line C) Use reference geometry to make an axis D) Any of the above will work -Answer- D) Any of the above will work I have a distance in my sketch preceded by a "sigma" symbol. This means... -Answer- It is a dimension driven by a parametric formula Graphical User Interface (GUI) -Answer- The format of information on the visual display of a computer, giving its user control of the input, output, and editing of the information primary modeling planes, principal viewing planes, or datum planes -Answer- The planes representing the XY-, XZ-, and YZ-planes in a Cartesian coordinate system. sketches -Answer- Collection of 2-D entities sketching editor -Answer- A software tool used to create and edit sketches. Profile -Answer- A planar sketch that is used to create a solid Extrusion -Answer- A solid that is bounded by the surfaces swept out in space by a planar profile as it is pulled along a path perpendicular to the plane of the profile Revolved solid -Answer- a solid formed when a profile curve is rotated about an axis Constraints -Answer- Geometric relationships, dimensions, or equations that control the size, shape, and/or orientation of entities in a sketch or solid model Geometrical Constraints -Answer- Definitions used to control the shape of a profile sketch through geometric relationships Dimensional Constraints -Answer- Measurements used to control the size or position of entities in a sketch. Algebraic Constraints -Answer- Constraint that define the value of a selected variable as the result of an algebraic expression containing other variables from the solid model. Variational techniques -Answer- Modeling techniques in which algebraic expressions or equations that express relationships between a number of variables and constants, any one of which can be calculated when all of the others are known. Parametric techniques -Answer- Modeling techniques where all driven dimensions in algebraic expressions must be known for the value of the dependent variables to be calculated. Driven Dimension -Answer- A variable connected to an algebraic constraint that can be modified only by user changes to the driving dimensions. Ground Constraint -Answer- A constraint usually applied to a new sketch to fix the location of the sketch in space. Regeneration -Answer- The process of updating the profile or part to show its new shape after constraints are added or changed Protrusion -Answer- A feature created by the addition of solid volume to a model Cut -Answer- A feature created by the removal of solid volume from a model Sketching Plane -Answer- A plane where 2-D sketches and profiles can be created. Blind Extrusion -Answer- An extrusion made to a specified length in a selected direction. Extrude to the next surface -Answer- An extrusion begins at the profile and the protrusion or cut stops when it intersects the next surface encountered Extrude to a selected surface -Answer- an extrusion where the protrusion or cut begins on the sketching plane, and stops when it intersects a selected surface [Show More]
