The following readings were taken with a tachometer on to a vertical staff. Horizontal Distance Stadia Readings 46.20 m 0.780; 1.010; 1.240 51.20 m 1.860; 2.165; 2.470. Calculate the tacheometric constants. Correct Answer 100, 0.20 m

D = Ks + C, where the constant K is equal to (f /i). It is called multiplying constant of the tachometer and is generally kept as 100. The constant C is equal to (f + c). It is called an additive constant.

Match the following, in the context of the leveling staff. a. Self-reading staff 1. The smallest division is 5 mm. its length is about 3 metres. b. Solid Staff 2. It has a moving target against which readings are taken by the staff man. The sliding target comes along with the vernier. c. Telescopic Staff 3. The readings are always taken from the telescope hence appear inverted. Therefore, readings are taken from downwards. d. Target staff 4. It has three telescopic lengths of 1.5, 1.5, and 2 meters when stretched out fully. Normally, its total length is 5 metres
Stadia readings were taken with a theodolite on a vertical staff with the telescope inclined at an angle of depression of 3o30′. The staff readings were 2.990, 2.055 and 1.120.
