Week 5

Which of the following is NOT a correct rule for dimension placement?

• Dimensions should not be duplicated in multiple views.

• Hidden lines should be used to show dimensions when necessary.

• Dimensions should be placed outside the object when possible.

• Centerlines can be used as reference points for dimensions.

What is the purpose of section lines in sectional views?

• To represent hidden features of an object.

• To show the cutting plane line.

• To indicate the areas where material has been cut away.

• To highlight important dimensions.

Which line type is used to indicate hidden features in a technical drawing?

• Continuous thin line

• Chain line

• Phantom line

• Dashed line

In dimensioning, what does the symbol "Ø" represent?

• Radius

• Diameter

• Angle

• Length

What does the symbol "R" indicate in a technical drawing?

• Rectangular feature

• Right-hand thread

• Radius

• Roughness

Which of the following is NOT a basic principle of dimensioning?

• Place dimensions outside the views whenever possible.

• Avoid crossing dimension lines.

• Ensure dimensions are readable and aligned properly.

• Use redundant dimensions to increase clarity.

Which of the following is NOT a standard element of dimensioning?

• Extension lines

• Dimension lines

• Section lines

• Leader lines

What is the primary reason for using different scales in technical drawings?

• To make drawings look more complex

• To ensure the drawing fits within the paper size while maintaining proportions

• To reduce the number of dimensions needed

• To eliminate the need for multiple views

If a drawing is labeled with a scale of 2:1, what does this mean?

• The drawing is half the size of the actual object

• The drawing is twice the size of the actual object

• The drawing and the actual object are the same size

• The drawing is reduced by a factor of two

What is the correct way to dimension a small arc in a sectional view?

• Use a dimension line with two arrows

• Use a dashed extension line

• Use a leader line with an "R" before the value

• Use the "Ø" symbol
