Question 1

When a cutting plane extends completely through an object, usually along a centerline, ____.
A) the cutting plane line is marked with an identifying letter
B) a full section is shown
C) the cutting plane arrows show the direction of sight
D) both b and c
E) all of the above

Accepted Answer

When a cutting plane extends completely through an object, a full section is shown and the cutting plane arrows show the direction of sight. Additionally, the cutting plane line may be marked with an identifying letter. Therefore, both options B and C are correct.

Question 2

Used typically for symmetrical objects; the cutting-plane line actually cuts through one quarter of the part. The sectional view shows half of the interior and half of the exterior at the same time.
A) Full section
B) Half section
C) Broken out section
D) Removed section
E) none of the above

Accepted Answer

A half section is used for symmetrical objects and shows half of the interior and half of the exterior at the same time. The cutting-plane line actually cuts through one quarter of the part.

Question 3

The cutting plane is offset through staggered interior features of an object to show those features in section as if they were in the same plane.
A) Aligned section
B) Removed section alignment method
C) Broken out section
D) Offset section
E) Use a revolved section broken away so the section can be dimensioned.

Accepted Answer

The description provided matches the definition of an offset section. This method is used to show internal features that are not in the same plane, by offsetting the cutting plane to expose them.

Question 4

Three different materials are shown in the section view of an object. The upper portion is made of a bronze material and is a horizontal rectangular piece. Under the bronze material, the remaining space is evenly divided vertically with a steel material on the left and a cast iron material on the right. Which of the following is (are) true?
A) If the bronze section lines are drawn at a 45° angle, then the steel and cast iron section lines could be drawn at a 135° angle.

D) If the bronze section lines are drawn at a 135° angle, then the steel section lines could be drawn at a 45° angle, and the cast iron section lines could be drawn at a 60° angle.
E) none of the above

Accepted Answer

The answer of Three different materials are shown in the...

Question 5

A sectional view established by revolving 90 degrees, in place, into a plane perpendicular to the line of sight, generally used to show the cross section of a part or feature that has consistent shape throughout the length.
A) Removed section
B) Revolved section
C) Aligned section
D) Offset section
E) none of the above

Accepted Answer

A revolved section is established by revolving 90 degrees into a plane perpendicular to the line of sight. This type of section is used to show the cross-section of a part or feature that has a consistent shape throughout its length. The other options (removed section, aligned section, and offset section) do not accurately describe this type of sectional view.

Question 6

A sectional view taken from the location of the section cutting plane and placed in any convenient location of the drawing, generally labeled in relation to the cutting plane.
A) Removed section
B) Revolved section
C) Auxiliary section
D) Broken out section
E) none of the above

Accepted Answer

A removed section is a sectional view taken from the location of the section cutting plane and placed in any convenient location of the drawing, generally labeled in relation to the cutting plane. This is the most appropriate choice for the given description. Revolved section is a sectional view obtained by rotating the object about an axis through space. Auxiliary section is a sectional view obtained by a secondary auxiliary cutting plane. A broken out section is a partial section view that is used when it is required to show only certain portions of a sectioned piece.

Question 7

An advantage of a removed section has over a revolved section is that ____.
A) a great deal of detail can be shown more effectively if the section is removed
B) break lines are not necessary when using removed sections
C) the section can exactly be shown in the place where the cutting plane line is
D) both a and c
E) none of the above

Accepted Answer

A removed section allows for more detail to be shown effectively because it is taken out of the main view, allowing for a clearer and more detailed representation of the sectioned area.

Question 8

These can be used when a long object of constant shape throughout its length requires shortening.
A) Conventional breaks
B) Conventional revolution
C) Broken out section
D) Removed section
E) none of the above

Accepted Answer

Conventional breaks are used in technical drawings to represent long objects that have a constant shape throughout their length, allowing the object to be shortened for convenience without losing essential details.

Question 9

A sectional view taken from the location of the section cutting plane and placed in any convenient location of the drawing, generally labeled in relation to the cutting plane.
A) Removed section
B) Revolved section
C) Aligned section
D) Offset section
E) none of the above

Accepted Answer

A removed section is a sectional view that is cut away from the object and placed in a different location on the same or another drawing sheet. This type of section is commonly used when the removed portion of the object blocks the view of other details or when the removed section would be too small to show in true scale.

Question 10

A print of a cylindrical object shows a half section as one of its views. Which of the following is (are) not true?
A) The cutting plane line removes one quarter of the object.
B) The hidden lines of the side of the object that was not sectioned show as thin, light lines.
C) The centerline of the cylindrical object is omitted.
D) both b and c
E) none of the above

Accepted Answer

A) The cutting plane line removes one half of the object, not one quarter.
B) The hidden lines of the side of the object that was not sectioned show as thick, dark lines, not thin, light lines.
C) The centerline of the cylindrical object is omitted in a half section view.

Question 11

A cube-shaped object is shown on the print. The object is made up of cast iron and has several circular depressions placed at random on three surfaces. Which of the following is (are) true?
A) A full section will probably describe the internal construction of the object adequately.
B) A half section will probably describe the internal construction of the object adequately.
C) An offset section will probably describe the internal construction of the object adequately.
D) Multiple removed sections will probably describe the internal construction of the object adequately.
E) none of the above

Accepted Answer

Multiple removed sections are likely needed to adequately describe the internal construction of the object, especially because the circular depressions are placed at random on three surfaces, indicating complexity that a single section might not fully capture.

Question 12

When one-half of an object is removed to be able to see the remaining section, a(n) ____ has been used.
A) half section
B) removed section
C) aligned section
D) offset section
E) none of the above

Accepted Answer

The answer of When one-half of an object is removed...

Question 13

A portion of a part is broken away to clarify an interior feature; there is no associated cutting-plane line.
A) Aligned section
B) Conventional break
C) Broken out section
D) Revolved section
E) none of the above

Accepted Answer

A broken-out section is used to show an interior feature of a part without the need for a cutting-plane line, by breaking away a portion of the part.

Question 14

What is the difference between a regular removed section and a section that has been removed by the alternate removed section method?
A) A removed section is labeled to match the cutting plane line, whereas a section removed by the alternate removed section method is not labeled in this way.
B) A removed section can be placed almost anywhere on the drawing sheet, whereas a section removed by the alternate removed section method is placed in a particular area.
C) A removed section shows the entire view except for hidden lines, whereas a section removed by the alternate removed section method is similar to a revolved section in that only the portion that is indicated as being removed is shown as rotated.
D) both a and c
E) all of the above

Accepted Answer

Both a removed section and a section removed by the alternate removed section method are labeled to match the cutting plane line. Both can be placed almost anywhere on the drawing sheet. A removed section shows the entire view except for hidden lines, whereas a section removed by the alternate removed section method is similar to a revolved section in that only the portion that is indicated as being removed is shown as rotated.

Question 15

A long object has a constant shape along its entire length. It is made of 3mm thick steel, and is bent in two areas along its entire length so that viewing it from the end, it looks roughly like the letter "S". Choose the best option seen on a print for this object from the following suggestions.
A) Use a revolved section broken away so the section can be dimensioned and section lines put in.
B) Use an auxiliary section projected directly from the view of the cutting plane line.
C) Use a broken out section with a small break line to clarify the interior dimensions.
D) Use a conventional revolution so that the object will not be distorted by foreshortening.
E) Use a revolved section broken away so the section can be dimensioned.

Accepted Answer

A revolved section broken away allows for the clear depiction of the object's cross-sectional shape and dimensions without distorting its appearance, making it ideal for an object with a constant shape along its length that resembles the letter "S" when viewed from the end.

Question 16

A cutting plane line is used in all but which of the following?
A) a full section
B) an auxiliary section
C) a broken out section
D) an alternate removed section
E) both c and d

Accepted Answer

A cutting plane line is not used in a full section as the entire object is shown without cutting it. The cutting plane line is used to indicate the imaginary cutting plane to show the internal features of the object in the section. It is used in an auxiliary section, broken out section, and alternate removed section. Therefore, option E is the correct choice as it excludes both options C and D.

Question 17

An alternate practice for providing removed and sectional views.
A) Alternate method
B) Rotated method
C) Arrow method
D) Removed method
E) none of the above

Accepted Answer

The arrow method is an alternate practice for providing removed and sectional views in technical drawings.

A) has a cutting plane line placed through the object to show where the section is taken
B) can be drawn to a larger scale so close detail can be more clearly identified
C) should be labeled to correspond with the cutting plane line
D) all of the above
E) none of the above

Accepted Answer

The answer of A revolved section ____.
A) has a cutting...

Question 19

When an offset section is used, ____.
A) the section shows dark vertical lines where the cutting plane lines changed direction at 90°
B) hidden lines and centerlines are usually ignored
C) the cutting plane line normally extends completely through the object to clearly display the location of the section
D) the cutting plane line is drawn completely through the object usually along a center plane
E) none of the above

Accepted Answer

The answer of When an offset section is used, ____.
A)...

Question 20

A cylindrical object with a constant shape has a 28 cm hole drilled in it from one end of the object to within 10 cm of the other end. Another smaller hole is drilled in the object from the side of the object at a 45° angle through to the drilled hole in the middle of the object. The smaller hole intersects the center drilled hole at 4 cm from the bottom of the center drilled hole. Choose the best option for this object shown on a print from the following suggestions.
A) A revolved section broken away so the section can be dimensioned and section lines put in.
B) An auxiliary section projected directly from the view of the cutting plane line.
C) A broken out section with a small break line to clarify the interior dimensions.
D) A conventional revolution so that the object will not be distorted by foreshortening.
E) A revolved section broken away so the section can be dimensioned.

Accepted Answer

A broken out section with a small break line to clarify the interior dimensions will be the best option as it will clearly show the interior features of the object, including the drilled holes and their positions in relation to each other. This will also help in dimensioning the object accurately. A revolved section may distort the object's features, and an auxiliary section may not provide a clear view of the interior.
