MAE 1351 EXAM 3 2024 WITH 100% CORRECT ANSWERS What are some problems with pictorials? - correct answer the distortion of angles, the distortion of true lengths, the distortion of Internal measurements, the distortion of curves Then the general rule for presenting the object becomes: - correct answer "Start with the preferred configuration; then add or subtract whatever views are necessary to best show all of the geometry." An axonometric drawing refers to three types of pictorial d...

tolerance - CORRECT ANSWER the amount of which dimensions in a component may vary, while still returning its ability to perform less tolerance - CORRECT ANSWER what is better less tolerance or more tolerance? 25.4 - CORRECT ANSWER 1inch to mm? thousandth, thou, or mil - CORRECT ANSWER what is 1/1000 of an inch called? 3 to 4 thou - CORRECT ANSWER how thick is a sheet of paper? +-.2in - CORRECT ANSWER whats the tolerance to a part dimensioned to 1 decimal place? +-.01 - CORRECT ANSWER...

A part may be properly represented on an engineering drawing with has few as... - CORRECT ANSWER One drawing (objects like sheet metal or gaskets have very little thickness so they can be represented with just the top view) Associated with the European method of creating the orthographic projections where you see the front face and draw what you see in the back. Same with top showing on bottom and right showing on the left. - CORRECT ANSWER First-Angle American form of creating orthogr...

Profile - CORRECT ANSWER a completed sketch that is used to create a solid Tangent - CORRECT ANSWER Touching but not intersecting Constraints - CORRECT ANSWER the geometric relationships, dimensions, or equations, that control the size, shape, and orientation and include assumptions that the CAD sketcher makes Implicitly defined - CORRECT ANSWER hidden from the sketcher Coincident - CORRECT ANSWER forces two points to coincide Concentric - CORRECT ANSWER makes the centers of arcs or cir...

ECHO 360 and Module Quizzes - CORRECT ANSWER ECHO 360 and Module Quizzes An assembly cannot be nested inside an existing assembly; only parts can - CORRECT ANSWER False I bring a part into an assembly in SolidWorks, and click the OK check mark at the top right. This will.. - CORRECT ANSWER leave the part in a floating state; align component with the assembly origin I bring a cube into an assembly and mate-coincident one of its edges to a fixed edge. It now has how many DOF's - CORR...

GD&T - CORRECT ANSWER (Geometric dimensioning and tolerancing) A 3-D mathematical system that allows a designer to describe the form, orientation, and location of features on a part within precise tolerance zones. Advantages of GD&T - CORRECT ANSWER 1) The system allows the designer to clearly specify design intent. 2) There is better communication throughout the design process. 3) The system is set up so that almost nothing can be interpreted in more than one way. 4) A datum reference...

The engineering design process follows the same steps as the scientific discovery process, or scientific method. True? - CORRECT ANSWER No; there are major differences The term "IPS" in SolidWorks refers to... - CORRECT ANSWER measurement units To create an extrusion, I must first draw a sketch on a surface. True? - CORRECT ANSWER Yes, but the surface must be flat What are the fundamental types of sketch constraints? - CORRECT ANSWER Geometrical and dimensional To clock a hexagonal...

boundary conditions - CORRECT ANSWER constraints and loads added to the boundaries of a finite element model interference - CORRECT ANSWER amount of overlap between two instances in an assembly clearance - CORRECT ANSWER minimum distances between two instances in an assembly arc - CORRECT ANSWER A curved entity that represents a portion of a circle boundary boxes - CORRECT ANSWER A square box used to sketch circles or ellipses tick mark - CORRECT ANSWER A short dash used in sketchin...

MAE 1351 EXAM 3 2024 COMPLETE QUESTIONS AND ANSWERS ALREADY PASSED Total runout (runout tolerance)[two arrows] - CORRECT ANSWER 3D control for rotating parts relative to a datum axis. (cylindrical surface = controls circularity, straightness, taper, concentricity, and surface profile; flat surface = controls wobble, perpendicularity, and flatness) Basic dimensions (those with a box around them)... - CORRECT ANSWER are theoretically exact and locate the perfect position of features fr...
