You must set a marker at a certain
point from traverse stations
3 + 00 and 4 + 25.
The angle from
the traverse line to station
3 + 00 and the distance between
the point and station 4 + 25 are
given.
How should you proceed to
set the point?
1.
Solve for the other angle from
the base line, and the
distance of the point from the
other station; then, set the
point by using transit and
tape.
Check the distance and
other angle from base line
2.
Solve for the angle from the
base line to the distance line
and set the point by the use
of transit and tape and check
by measuring the base line
3.
Lay out the lines to the point
with tape and straddlers and
check with a transit
4.
Lay out the lines to the point
with tape and straddlers and
check by remeasuring one leg
of the triangle
10-59.
When tying in a point to a station
on a traverse, which of the
following conditions should you
carefully consider?
1.
The selected tie station
should not be easily disturbed
2.
The tie station must be
visible from the point to be
tied in
3.
Both 1 and 2 above
4.
The angle between the tie
lines should be no greater
than 90°
10-60.
A closed traverse was to be 15,000
feet in length.
The last course
was to be 3,000 feet in length.
After you turn the last deflection
angle and progress 3,000 feet on
the last course, you find that you
are 3 feet from the starting point
of the traverse.
What is the
order of precision?
1.
First
2.
Second
3.
Third
4.
Fourth

2.
0.528 ft
3.
0.759 ft
4.
1.255 ft

telescope is not perpendicular
to the vertical axis
3.

levels is not perpendicular to
the vertical axis of the
telescope
4.

Errors that can lead to inaccurate
surveying when you use a transit
may include which of the following
natural errors?
1.
