How much does an Invar tape expand and contract due to change in temperature, compared to a standards steel tape under the same conditions?
(a) An Invar tape expands and contracts much more than a steel tape
(b) An Invar tape expands and contracts slightly less than a steel tape
(c) An Invar tap expands and contracts much less than a steel tape
(d) The two tapes expand and contract about the same amount - correct answer (c)
An Invar tape will expand and contract much less than a steel tape when exposed to the same change in temperature. Unfortunately, Invar tapes, while extremely accurate, are too fragile for normal use. So they are typically used for measuring baselines or calibrating steel tapes
How many pins are in a set of chaining pins?
(a) 10
(b) 11
(c) 12
(d) 20 - correct answer (b) 11
What features distinguish an add tape? (a) The last foot of each end is graduated in tenths or hundredths or a foot
(b) There is an extra graduated foot beyond the zero mark
(c) There is an extra graduated foot at the 100 foot end of the tape
(d) There is an extra graduated food at both ends of the tape - correct answer (b)
An add tape has an extra graduated foot beyond the zero mark
On a subtract tape, the last foot is graduated into tenths or hundredths
How long is a Gunter's Chain?
(a) 30 ft
(b) 53 ft
(c) 66 ft
(d) 130 ft - correct answer (c) 66 ft
The area of a square one Gunter's chain on a side is most nearly
(a) 250 ft^2
(b) 4400 ft^2
(c) 10,000 ft^2 (d) 44,000 ft^2 - correct answer (b) 4400 ft^2
( 66 ft )^s = 4356 ft^2
Most, nearly, what is the area of a rectangle 6 Gunter's chains long by 5 Gunter's chains wide?
(a) 3 ac
(b) 7 ac
(c) 20 ac
(d) 30 ac - correct answer (a) 3 ac
(6 x 66 ft) * (5 x 66 ft)
------------------------ = 3 ac
43,560 ft^s / ac
The term "height of instrument," as used in leveling, means
(a) the distance from the ground to the axis of the telescope
(b) the elevation of the line of sight above the datum being used
(c) the height of the line of sight above a bench mark
(d) all of the above - correct answer (b) the elevation of the line of sight above the datum being used Balancing distances to backsights and foresights eliminates
i. collimation error
ii. curvature of the earth errors
iii. rod plumb errors
(a) i only
(b) ii only
(c) i and iii only
(d) i and ii only - correct answer (c) by balancing distances to backsights and foresights, both curvature of
the earth error and collimation error are eliminated
Refraction error is eliminated by line of sight not being close to the ground
Rod plumb error is eliminated by user being careful
Parallax error is eliminated by adjusting eye piece
The curvature of the earth error associated with lebeling shot of 1000 ft is most nearly
(a) 0.024 ft
(b) 0.032 ft
(c) 0.035 ft
(d) 0.055 ft - correct answer (a) 0.024 ft
C = 0.024 * F^2
