True or False. Odometer is a device for counting pace which is strapped to the leg of the pacer.
True
False
True or False. The tape lengthens as the temperature falls and shortens are the temperature rises.
True
False
True or False. Leveling rod is used as guides or markers when sighting points and for lining up tapemen in order to keep them going along the correct direction.
True
False
True or False. The first rule in taping correction is when a line is measured with a tape that is 'too short', the corrections are applied to the observed length by adding.
True
False
True or False. When a specified or required length is to be laid out with a tape that is 'too long'. The corrections are subtracted from the known length.
True
False
True or False. When a specified or required length is to be laid out with a tape that is 'too short'. The corrections are subtracted from the known length.
True
False
True or False. When a specified or required length is to be measured with a tape that is 'too short'. The corrections are subtracted from the known length.
True
False
True or False. The correction due to alignment can be calculated employing the slope correction formula.

A line measured with 50-m long was determined to be 645.22 m when the average temperature during taping was 15.75°C. If the tape is of standard length at 20°C and the coefficient of thermal expansion of steel is 0.0000116/°C, the correct length of the measured line is (a)
A surveyor counted 50,52,53,51,53, and 51 paces in walking along 45-m course laid out on a concrete pavement. He then took 768,771,772,770, 769 and 770 paces in walking an unknown distance XY. Determine the length of XY.
(a)
Two points A and B are established along the same direction from a theodolite station. If the subtended angle read on a subtense bar held at A and B are 0°55’20” and 0°23’44” , respectively, the horizontal distance between two points is (a) .
A line measured with a 30-m steel tape was recorded as 325.70 m. If the tape is found to be 30.05 m long during standardization, the correct length of the line is (a) .
A slope distance of 465.82m is measured between two points with a slope angle of 12°35”. The corresponding horizontal distance between the point is (a) .
