MAE 1351 EXAM SCRIPT 2026 QUESTIONS
WITH ANSWERS
◉ Basic dimensions (those with a box around them)... Answer: are
theoretically exact and locate the perfect position of features from
clearly identified datums
◉ The feature control frame Answer: contains the geometric
characteristic symbol, the geometric tolerance, and the relative
datums
◉ Free running fit Answer: 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 Answer: tolerance; right
◉ ASME stands for Answer: American Society of Mechanical
Engineers
◉ Most drawings conform to the ______ system or they conform to
the ____ system Answer: SI; U.S. Customary
,◉ Where the dimension is less than one millimeter... Answer: a zero
precedes the decimal point
◉ Where the dimension is a whole millimeter... Answer: neither the
decimal point nor the zero is shown
◉ Where the dimension exceeds a whole number by a decimal
fraction of one millimeter... Answer: 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 Answer:
false
◉ T/F A zero is not used before the decimal point for values less
than one inch Answer: true
◉ contour rule or contour dimensioning Answer: 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 Answer: false, they should only apper once
, ◉ Dimensioning and tolerancing shall be complete so that... Answer:
there is full understanding of the characteristic of each feature
◉ circles are typically dimensioned as Answer: diameters
◉ arcs are dimensioned as Answer: radii
◉ T/F you should give dimensions between holes vs dimensioning
the holes from the end of the part Answer: True
◉ Baseline Dimensioning Answer: all of the dimensions in a given
direction originate from a base or datum (frequently used for CNC
machines)
◉ Chain Dimensioning Answer: features are dimensioned relative to
one another (used when a part function requires that features be
related to one another)
◉ T/F chain dimensioning is often preferred over baseline Answer:
False, Baseline dimensioning is prefrred
◉ Chain dimensioning usually yields the _______ accumulation of
tolerance between features,where the maximum distance between
