Engineering Fits and Tolerances Quiz

What is the engineering term for the consideration of how parts fit together?

• Nominal

• Tolerance

• Fits and tolerances

• Manufacturing processes

What is the purpose of specifying a tolerance in engineering design?

• To allow for variation from the nominal dimension

• To limit the manufacturing processes

• To make the part exactly to the nominal dimension

• To increase the cost of manufacturing

What is the consequence of selecting tolerances that are far tighter than necessary?

• Limited manufacturing processes

• Decreased cost of manufacturing

• Exponential growth in the cost of manufacturing

• No impact on the cost of manufacturing

What type of fit is intended to be a permanent connection and usually requires a press to assemble?

• Force fit

• LT3

• LC9

• LC11

What is the purpose of the chart showing a variety of different manufacturing processes and their corresponding tolerance capability?

• To show the general idea of the tolerance that can be expected

• To increase the cost of manufacturing

• To show the cost of manufacturing processes

• To limit the manufacturing processes

What is the primary reference for designing fits in the inch system?

• ISO 286-2

• ASME fits

• Metric fits

• Machinery's Handbook

Product Variation in Manufacturing

• Difference between an object and other objects of the same type or from a standard.

• The act of creating a new product
• Different versions or options available for a car

• The removal of a product from the market

Accuracy is a measure of how close a __________ comes to the actual/true value of what is being measured.

Precision

• how close a series of measurements are to one another, irrespective of the actual value.

• how far a series of measurements are to one another, irrespective of the actual value.

• how approximation is used in a series of measurements.

• how Inaccurate or imprecise measurements are to each other.

Variance in measurements

• The average of the values in a data set
• The lowest value in a data set
• Measure of how spread out the values in a data set are
• The highest value in a data set
