C) 120°
D) 135°

Question 13

To define the location of the imaginary sectional plane, a(n) _____ is drawn on the view where the cut was made.

A) cutting plane line
B) crosshatch
C) thin wall line
D) offset line

Question 14

Where the cutting plane passes through solid material, _____ lines are drawn.

B) inside of the view
C) outside of the view
D) wherever there is adequate space

Question 17

Nuts and bolts should not be section lined.

Question 18

When crosshatching, you should always take the time to measure the spacing.

Question 19

Sectional views are used to show the size and shape of the exterior of an object.

Question 20

A cutting plane typically extends through an object in a straight line.

Question 21

The spacing of crosshatching lines:

A) should be 1/16"
B) should be 1/8"
C) should be 1/4"
D) will vary depending on the size of the section

Question 22

Imagine that you have used the universal crosshatching symbol rather than the standard material section-lining symbol on a drawing. What should you do?

A) start over with a new drawing
B) place a note near the section to indicate the type of material
C) remove the crosshatching and replace it with the standard material section-lining symbol
D) nothing-the use of the universal crosshatching symbol is appropriate by itself and requires no further action or notation

Question 23

Imagine that the sectional details for a part you are drawing are too small to be interpreted and dimensioned. What should you do?

A) prepare auxiliary sections
B) prepare enlarged sections
C) eliminate very small details to simplify the drawing
D) prepare the sections as clearly as possible and add notations to explain details that are too small to be drawn

Question 24

Which of these should be section lined?

A) curved surfaces
B) spokes
C) ball bearings
D) gear teeth

Question 25

Imagine that you have drawn a part and used crosshatching consisting of thin sharp lines at 45°, then realize that an adjacent part also needs to be crosshatched. What should you do?

A) omit crosshatching on the adjacent part to prevent confusion
B) label the adjacent part as "sub-crosshatched"
C) use identical crosshatching for the adjacent part
D) crosshatch the adjacent part using reversed lines

Question 26

When offsetting cutting plane lines, you should always:

A) bend the line at right angles to the cutting plane and perpendicular to the plane of projection
B) maintain straight lines that run parallel to the plane of projection
C) show any bends in the cutting plane in the sectioned view
D) omit special features such as a countersunk hole or a slot

Question 27

Imagine that you are drawing an object that includes a spoked wheel that does not align with the cutting plane. What should you do when projecting the sectional view?

A) rotate the object and section line the spoke
B) rotate the object and refrain from section lining the spoke
C) draw the projection using straight line separations
D) draw the projection without any modification

Question 28

B) with two straight lines that form a 45° angle
C) with an irregular short break line
D) with a semicircular long break line

Question 29

What type of section is used when only a small part of an object needs to be sectioned?

A) half-section
B) broken-out section
C) offset section
D) full section

Question 30

When are half-sections used?
