In which of the following
situations should the breaking tape
method of measuring be used?
1.
Determining the horizontal
distance between points on
terrain havinq a 6-to-1 slope
ratio
2.
Measuring the width of major
access roads
3.
Measuring horizontal distances
in heavily wooded and
obstructed areas
4.
All of the above
9-29.
A two-man party is using the
breaking chain-procedure and a
100-foot tape to chain a line on a
steep slope.
When, if ever, does
the rear chainman give the front
chainman a chaining pin?
1.
Each time a 25-ft distance only
is measured
2.
Each time a 50-ft distance only
is measured
3.
Each time an even-foot distance
of less than 100 ft is measured
4.
Never

9-30.
Assume that you continue measuring
up the slope with a 100-foot tape.
The head chainman is holding zero
at point D.
What is the horizontal
distance between points C and D?
1.
10 ft
2.
15 ft
3.
25 ft
4.
30 ft
9-31.
The standard error of a 100-foot
tape can be determined in which of
the following ways?
1.
By
calibration
by the Bureau of
Standards
2.
By comparison with a length of
a calibrated 100-foot tape
3.
By comparison with a known
100-foot distance
4.
By each of the above means
9-32.
By calibrating a tape, you should
remember that the standard tension
and corresponding temperature for a
100-foot tape supported throughout
is
1.
5 lb, 65°F
2.
10 lb, 68°F
3.
15 lb, 68°F
4.
20 lb, 65°F
9-33.
A 100-foot tape has a standard
error of 0.003 feet.

total error for a taped distance of
471.56 feet?
(Round off to the
nearest 0.01 foot.)
1.

0.01 ft
3.
0.02 ft
4.
0.05 ft
9-34.
Under standard conditions, a tape
indicates 100.00 feet when it
actually should measure 99.996
feet .
Using this tape, how far
should you measure to set a point
450 feet away from another point?
1.
449.96 ft
2.
449.98 ft
3.
450.02 ft
4.
450.04 ft
9-35.
A tape has a standard error which
causes it to indicate 99.996 feet
when it is actually measuring
100.00 feet.
What is the actual
distance between two points if the
taped distance is 259.05 feet?
1.
259.04 ft
2.
259.05 ft
3.
259.06 ft
4.
260.00 ft
