Basic dimensions (those with a box around them)... - ANSWER-are theoretically exact and locate the perfect position of features from clearly identified datums The feature control frame - ANSWER-contains the geometric characteristic symbol, the geometric tolerance, and the relative datums Free running fit - ANSWER-not for use where accuracy is essential, but are good for large temperature variations, high running speeds, and heavy journal pressures A dimension is expressed to the same nu...

center of mass - ANSWER-origin of the coordinate axes for which the moments are zero moments of inertia - ANSWER-measure of an object's ability to resist rotational acceleration to rotate about an axis radii of gyration - ANSWER-distance from an axis where all of the mass can be concentrated and still produce the same moment of inertia density - ANSWER-mass per unit volume for a given material FEA (Finite Element Analysis) - ANSWER-advanced computer-based design analysis technique t...

What are some problems with pictorials? - 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: - 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 drawings: - ANSWER-isometric, dimetric, and trimetric drawings The...

Total runout (runout tolerance)[two arrows] - 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)... - ANSWER-are theoretically exact and locate the perfect position of features from clearly identified datums The feature control frame - ANSWER-contains the geometric ch...

boundary conditions - ANSWER-The constraints and loads added to the boundaries of a finite element model. center-of-mass (centroid): - ANSWER-The origin of the coordinate axes for which the first moments are zero. constraint - ANSWER-A boundary condition applied to a finite element model to prevent it from moving through space. density - ANSWER-The mass per unit volume for a given material. displacement: - ANSWER-A change in the location of points on an object after it has been ...
