1. Pacing is difficult in _______
a) Smooth surfaces
b) Plain areas
c) Rough ground
d) Plateaus
Explanation: Pacing is difficult in uneven grounds due to different slopes. That is because it becomes different as well as difficult to measure length of irregular ground accurately.
2. Instrument shaped like a watch and is carried in pocket or attached to one leg is _______
a) Pedometer
b) Odometer
c) Passometer
d) Speedometer
Explanation: Passometer is an instrument shaped like a watch and is carried in pocket or attached to one leg. Pedometer advantage on the passometer is that it registers total distance covered unlike a number of paces in passometer.
3. Which instrument mechanism is operated by motion of the body and it automatically registers the number of paces, thus avoiding the monotony and strain of counting the paces, by the surveyor?
a) Passometer
b) Pedometer
c) Odometer
d) Chaining
Explanation: Pedometer is a device similar to the passometer except that, adjusted to the length of the pace of the person carrying it. Passometer avoids the monotony and strain of counting the paces.
4. Which instrument registers total distance covered by any number of pace?
a) Passometer
b) Pedometer
c) Odometer
d) Chaining
Explanation: Pedometer advantage on passometer is that it registers total distance covered unlike number of paces in passometer.
5. Instrument for registering the number of revolutions of a wheel is _____
a) Odometer
b) Pedometer
c) Pedometer
d) Chaining
Explanation: Number of revolutions registered by Odometer can then be multiplied by the circumference of the wheel to get the distance. Pedometer advantage on passometer is it registers total distance covered unlike number of paces in passometer.
6. Most accurate method of direct measuring is with ________
a) Passometer
b) Pedometer
c) Theodolite
d) Chaining
Explanation: Theodolite measurement is not under direct measurements. Measurement with passometer, measurement with pedometer, pacing is based on the method of measuring the distances directly.
7. Which of the following is not under direct measurement?
a) Pacing
b) Chaining
c) Taping
d) Triangulation
Explanation: Triangulation is by optical means. Pacing is rough surveying. Chaining gives almost accurate readings. Taping gives accurate readings.
8. What is required to transfer points to the ground, while chaining along the sloping ground?
a) Spirit level
b) Plumb bob
c) Butt rod
d) Pegs
Explanation: It also transfers points from line ranger to the ground. Spirit level is the instrument used to level the plane table by adjusting the spirit bubble in it to center.
9. What is used for measuring offsets, but it is often used by building surveyors or architects?
a) Plum bob
b) Butt rod
c) Pegs
d) Laths
Explanation: It generally consists of two laths, each of 1 yard or 1 m in length loosely tiered together. Plumb bob is suspended at the center of the plane table to transfer the points on the plan to ground.
10. What is used in centering aid in theodolites, compass, plane table and variety of other surveying instruments?
a) Butt rod
b) Whites
c) Laths
d) Plumb bob
Explanation: Plumb bob transfers points to the ground so it is used for centering. Butt are used for measuring offsets.
