Accidental (random) errors in surveying are also called compensating errors because they:
सही उत्तर: क) Tend to be positive and negative equally and partly cancel each other
Random errors are equally likely to be plus or minus, so they partially compensate; systematic errors accumulate.

A basic principle of surveying is that a new point should be located by measurements from at least:
सही उत्तर: ग) Two points of reference already fixed
A point is fixed by measurements (distances or angles) from two known reference points, e.g. by two ties or a distance and angle.

A preliminary inspection of the area to be surveyed, to plan the survey and select stations, is called:

The ring and ball apparatus is used to determine which property of bitumen?
सही उत्तर: ग) Softening point
In the ring and ball test, the temperature at which bitumen softens enough for a steel ball to sink through it is the softening point.

-
The penetration test on bitumen measures its consistency (hardness) as the depth a standard needle penetrates, expressed in units of:
सही उत्तर: क) 0.1 mm
A penetration value of 60 means the needle penetrated 6 mm, i.e. 60 units of 0.1 mm, under standard load, time and temperature.
