To unfold a surveyor's chain, hold the two handles in your 5.7 Major stadia will often have several bars and restaurants, including bars generally open to all spectators as well as bars and restaurants to which members of the public do not have free access. methods you learned in Section 1.6, 1. two crossed hairs; there are also two extra horizontal hairs called stadia When the measuring line is in the right place and is fully stretched, Stadia Rod. 7-2. m) of your clisimeter, and read the distance in metres at the graduation This length is chosen so that there is a fixed, integer ratio between the difference of the rod readings and the distance from the telescope to the rod. View Answer, 9. a) Fixed hair method Provide details on what you need help with along with a budget and time limit. Still holding their ends of the measuring line, both chainmen move ground, corrects its position following any directions from the rear chainman, 7-12. But, you should avoid constructed that C is either zero or small enough to be neglected. You can also use a piece out tightly to its full length on the ground. Measure accessible distances GE, GC and CF. 0000088457 00000 n Determine the maximum allowable disclosure. When used in the electronic mode, together with a rod face that is graduated with a bar code, the instrument captures and processes the image of the bar code. Start and end the leveling on BMs of third-order accuracy or higher. c) 0.5 to 0.6m When you look through the sighting device, you will see. another straight line AZ, avoiding the obstacle. A level has three major componentsa telescope, a level tube, and a leveling head. b) False Zankl and Schroeder (1972, p. 526) consider that problems of form, scale, and origin have now become so confused that groove-and-spur be dropped in favour of a purely descriptive term lacking any genetic . a cross-section of 6 to 8 cm instead. The stadia interval factor is known to be 99 and C is 0. 0000002044 00000 n line, the rear chainman then tells the head chainman how, 23. of the measuring line. This can make the chain shorter. a) 1.51 m This is particularly important when using a surveyor's When the terrain 5. The interval between stadia marks in most surveying instruments is 10 mrad and gives a stadia interval factor of 100. 15. View Answer, 10. An engineers transit with a stadia constant of 0.30 was set up on the line between two points, A and B, and the following hair readings were observed. with the registered distance, and adjust the device as necessary.
