MAE 1351 EXAM 3 2025 QUESTIONS AND
ANSWERS
Total runout (runout tolerance)[two arrows] - ANS 3D control for rotating parts relative to a
datum axis. (cylindrical surface = controls circularity, straightness, taper, concentricity, and
surface profile; flat surface = controls wobble, perpendicularity, and flatness)
Basic dimensions (those with a box around them)... - ANS are theoretically exact and locate
the perfect position of features from clearly identified datums
The feature control frame - ANS contains the geometric characteristic symbol, the geometric
tolerance, and the relative datums
Free running fit - ANS not for use where accuracy is essential, but are good for large
temperature variations, high running speeds, and heavy journal pressures
A dimension is expressed to the same number of inches of decimal places as its ________.
Zeros are added to the _____ of the decimal point where necessary - ANS tolerance; right
ASME stands for - ANS American Society of Mechanical Engineers
Most drawings conform to the ______ system or they conform to the ____ system - ANS SI;
U.S. Customary
Where the dimension is less than one millimeter... - ANS a zero precedes the decimal point
1 Copyright ©2025 SIRJOEL ALL RIGHTS RESERVED
, Where the dimension is a whole millimeter... - ANS neither the decimal point nor the zero is
shown
Where the dimension exceeds a whole number by a decimal fraction of one millimeter... -
ANS the last digit to the right of the decimal point is not followed by a zero
T/F commas and spaces shall be used to separate digits into groups in specifying millimeter
dimensions on drawings - ANS false
T/F A zero is not used before the decimal point for values less than one inch - ANS true
contour rule or contour dimensioning - ANS each dimension should be placed in the view
where the contour shape is best shown
T/F Dimensions should appear multiple times in different views on a drawing - ANS false,
they should only apper once
Dimensioning and tolerancing shall be complete so that... - ANS there is full understanding of
the characteristic of each feature
circles are typically dimensioned as - ANS diameters
arcs are dimensioned as - ANS radii
T/F you should give dimensions between holes vs dimensioning the holes from the end of the
part - ANS True
Baseline Dimensioning - ANS all of the dimensions in a given direction originate from a base
or datum (frequently used for CNC machines)
