Option 2
Select the correct (i.e complete) top view of the object represented below:
3 views, the front, top and either the right or left side.
Select the correct choice (only one). In the following drawing, "x" marks the direction of sight of the front view. How many views should be sketched to fully represent the object using orthographic multiview projections? What views should these be?
True
T/F A cutting plane shows where the object is cut to show the section view.
True
T/F A cylindrical shape can be dimensioned by providing its height and the diameter of its base
True
T/F A depth auxiliary view can project from a rear view.
True
T/F A top view is a depth primary view because it shows depth in the direction away from the front view, from which it is projected.
False
T/F All dimensions below are independent of each other. The volume of water that the vessel in multiview projection below can hold depends on dimension "c".
True
T/F All dimensions below are independent of each other. The volume of water that the vessel in multiview projection below can hold depends on dimensions "b" and "e" only.
False
T/F An auxiliary section is an auxiliary view in section. They are used to properly show internal features that project true size/shape on primary planes of projection.
True
T/F An auxiliary view is a view that is formed from any point of view other than the 6 points of view that form the 6 primary views.
True
T/F Auxiliary views allow features that are not parallel to the primary planes of projection to appear true size and true shape.
False
T/F Auxiliary views are only used to show the true angle between features.
False
T/F Auxiliary views cannot be section views.
False
T/F Broken out sections are used to show potential defects that may arise from manufacturing.
True
T/F Circular faces appear as elliptical faces when viewed at an angle other than the normal to the circular face.
False
T/F Circular faces appear as hyperbolic faces when viewed at an angle other than the normal to the circular face.
False
T/F Common solid features such as webs, ribs, ball bearings, gear teeth, and threads are hatched when shown in section views.
True
T/F Consider the following part drawing. The perpendicularity tolerance shown increases as the diameter of the protrusion (datum B) decreases.
False
T/F Consider the position tolerance in the following feature control frame. Is the value of the position tolerance always 0.001 units?
True
T/F Cutting planes are identified by placing letters next to the arrow heads, and the section view is identified with a corresponding label that reads "Section + letters next to the arrow heads".
False
T/F Depth auxiliary views show height and width, but not depth; width auxiliary views show height and depth, but not width; height auxiliary views show width and depth, but not heigth.
True
T/F Dimensions should be given on visible features and not on invisible (hidden) features.
False
T/F First angle projections place the object in the third quadrant of a conventionally adopted coordinate system.
True
T/F Height auxiliary views show height, and project from a view that does not show height.
False
T/F Hidden lines are always needed on auxiliary views.
False
T/F Hidden lines should always be sketched in section views. If a line is hidden in a primary view, it will still be hidden in the section view that replaces the primary view.
True
T/F If an object is reoriented in space, relative to the primary planes of projection, views that were auxiliary views before the rotation may become primary views after the rotation.
True
T/F In GD&T, the departure from the specified material conditions is called "Bonus Tolerance"
True
T/F Miter lines are inclined at 45 degrees to the horizontal, and are used to sketch a third view form two views that are adjacent to each other.
False
T/F Superfluous dimensions are required because they facilitate reading the size of a feature in a set of orthographic multiview projections.
False
T/F Symmetry or center lines have precedence over visible lines. This means that when both symmetry/center and visible lines occupy the same location, the symmetry/center line is sketched, and the visible line is not sketched.

False
T/F The specification for position for the three holes on a "Support Plate" are as shown below. From the above, if all hole diameters are 0.377 units, the part would be acceptable.
True
T/F The specification for position for the three holes on a "Support Plate" are as shown below. Based on drawing proportions, the choice of primary and secondary datum features follows the rule that the primary datum feature should be the largest surface area, and secondary datum features should have smaller surface areas than the primary.
True
T/F Visible lines have precedence over hidden lines. This means that when both visible and hidden lines occupy the same location, the visible line is sketched, and the hidden line is not sketched.
True
T/F A leader line is a thin solid line directing attention to a note or dimension.
False
T/F A triangular shape can be dimensioned by giving one of the triangle's internal angles and one of the triangle's external angles, since providing two of the angles of a triangle fixes the triangle.

T/F Dimensions should be given on the side of a view that is adjacent to another view.

No
The radial deviation from true position of the axis of a pin is 0.020 in. If the position tolerance calls for a diametral tolerance of 0.025 in regardless of feature size (RFS), is the actual pin located within position tolerance?
