IED - Types of Tolerances in Engineering

What is the purpose of specifying tolerances in engineering drawings?

• To increase the cost of manufacturing

• To indicate the acceptable amount of variation in dimensions

• To ensure all parts are identical

• To reduce the need for quality control

Which tolerance format allows for variation in only one direction?

• Bilateral Tolerance

• Unilateral Tolerance

• Limit Dimensions

• General Tolerance

• 0.03 inches

• 0.06 inches

• 0.09 inches

• 0.12 inches

• 1.45 inches

• 1.50 inches

• 1.55 inches

• 1.60 inches

Which of the following is a characteristic of bilateral tolerance?

• Allows variation in only one direction

• Provides an upper and lower limit

• Permits variation in both directions

• Does not specify any variation

• 2.98 inches

• 2.99 inches

• 3.01 inches

• 3.02 inches

What is the main reason for using general tolerances in engineering drawings?

• To reduce the number of dimensions

• To ensure all dimensions have a specified tolerance

• To increase the complexity of the drawing

• To eliminate the need for specific tolerances

Which tolerance format provides both an upper and lower limit for a dimension?

• Unilateral Tolerance

• Bilateral Tolerance

• Limit Dimensions

• General Tolerance

• 3.98 to 4.02 inches

• 3.99 to 4.01 inches

• 4.00 to 4.02 inches

• 4.02 to 4.04 inches

What is the total permissible variation (range) for a dimension with limit dimensions of 5.005 inches and 4.995 inches?

• 0.005 inches

• 0.010 inches

• 0.015 inches

• 0.020 inches
