Question 1

The ____________ material condition for a part exists when a hole is at its lowest limit of size, or when a shaft is at its highest limit of size.&#10;A)LMC&#10;B)MMC&#10;C)RFS

Accepted Answer

The Maximum Material Condition (MMC) exists when a part contains the maximum amount of material within its specified limits; for a hole, this is its smallest size, and for a shaft, it is its largest size.

Question 2

Parallelism can be applied to a surface or an axis.

Accepted Answer

Parallelism in geometric dimensioning and tolerancing can be applied to both surfaces and axes to ensure they are parallel to a datum plane or axis.

Question 3

If neither MMC or LMC is specified:&#10;A)LMC&#10;B)MMC&#10;C)RFS

Accepted Answer

B

Question 4

A tolerance zone defined by two flat planes, between which a surface must fall, applies to:&#10;A)Concentricity&#10;B)Flatness&#10;C)Roundness&#10;D)Cylindricity

Accepted Answer

Flatness is the geometric tolerance that defines the tolerance zone between two parallel planes within which the entire surface must lie. Concentricity, roundness, and cylindricity involve circular or cylindrical feature requirements, not flat planes.

Question 5

The ____________ material condition for a part exists when a feature contains the minimum amount of material.&#10;A)LMC&#10;B)MMC&#10;C)RFS

Accepted Answer

LMC stands for Least Material Condition, which is the condition where a feature contains the minimum amount of material, hence making it the correct choice.

Question 6

Position tolerances always require a reference to one or more datums.

Accepted Answer

Position tolerances in geometric dimensioning and tolerancing (GD&T) specify the allowable variation in the location of a feature relative to other features or datums, thus requiring reference to one or more datums to establish a reference frame for measurement.

Question 7

____________ affect the amount of tolerance if the actual size of a feature differs from the MMC or LMC that is specified.&#10;A)Modifiers&#10;B)Datums&#10;C)Geometric characteristic symbols&#10;D)All of the above

Accepted Answer

Modifiers affect the amount of tolerance by specifying conditions like Maximum Material Condition (MMC) or Least Material Condition (LMC), which adjust the tolerance based on the actual size of the feature.

Question 8

____________ appear in the same box as, and to the right of a tolerance.&#10;A)Modifiers&#10;B)Datums&#10;C)Geometric characteristic symbols&#10;D)All of the above

Accepted Answer

Modifiers are used in the context of geometric dimensioning and tolerancing (GD&T) to provide additional information about the tolerance specified. They appear in the same box as the tolerance value, to the right of it, to modify or provide more detail about how the tolerance is to be interpreted.

Question 9

The tolerance zone for perpendicularity:&#10;A)Is always a zone between two parallel planes&#10;B)Is always a cylindrical zone&#10;C)May be a zone between two parallel planes or a cylindrical zone&#10;D)&#8203;

Accepted Answer

The tolerance zone for perpendicularity in geometric dimensioning and tolerancing can either be between two parallel planes or a cylindrical zone, depending on the specified requirements of the part or feature being measured.

Question 10

Orientation tolerances include:&#10;A)Straightness and parallelism&#10;B)Parallelism and total runout&#10;C)Parallelism and angularity&#10;D)Concentricity and perpendicularity

Accepted Answer

Orientation tolerances include parallelism and angularity, which define the orientation of features relative to each other or to the datum.

Question 12

When concentricity is specified:&#10;A)The two features must be located on the same axis&#10;B)One of the two features must be the datum for the other&#10;C)The tolerance zone will be a cylinder&#10;D)All of the above are true&#10;E)Only a and b are true&#10;F)Only a and c are true

Question 15

____________ tolerances control the shape of arcs, part contour, or other irregular surfaces.&#10;A)Profile&#10;B)Form&#10;C)Position&#10;D)Orientation
