Quiz on Tolerances in Drawings

What is the definition of tolerances in a drawing?

• The exact dimensions of a part

• Allowances for a dimension that are permitted when making or machining a part

• The total weight of a component

• The aesthetic design of a part

If a dimension is given as 0.500 +/- 0.005, what is the maximum material condition (MMC) of this dimension?

• 0.495

• 0.500

• 0.505

• 0.510

What is the minimum material condition (LMC) for a dimension of 0.500 +/- 0.005?

• 0.500

• 0.495

• 0.505

• 0.510

In the example of an unequal bilateral tolerance, 0.500 +0.007/-0.003, what is the MMC?

• 0.507

• 0.500

• 0.503

• 0.497

For the same example, what is the LMC?

• 0.507

• 0.500

• 0.497

• 0.503

Which of the following describes a unilateral tolerance?

• A tolerance that is both above and below the nominal dimension

• A tolerance that is only above the nominal dimension

• A tolerance that is only below the nominal dimension

• A tolerance that is either above or below the nominal dimension

What is a scale drawing?

• A drawing that shows all dimensions at actual size

• A drawing that is smaller or larger than the actual part size

• A drawing that includes exploded views

• A drawing that shows only the assembly of parts

Which of the following is NOT a type of drawing mentioned in the notes?

• Detail drawing

• Assembly drawing

• Perspective drawing

• Sub-assembly drawing

An exploded view drawing is primarily used for:

• Showing the aesthetic design of a part

• Understanding the assembly process of components

• Providing detailed dimensions

• Comparing material types

If a question on a drawing asks for the height of a component, which of the following should you provide?

• The weight of the component

• The height measurement indicated on the drawing

• The color of the component

• The material used
