MAE 1351 EXAM 1
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...
- Select a plain line from the sketch to use as an axis
- Make an axis in the sketch using a construction line
- Use reference geometry to make an axis
- 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 1 / 2
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
