Precise rods have a built-in circular bubble level to maintain the plumb of the rod. method itself. of each survey, check for this by sliding the entire length of the chain free: . An instrument equipped for stadia work has two horizontal stadia marks spaced equidistant from the center crosshair of the reticle. The term stadia is now applied to the cross hairs and rod used in making measurements, as well as to the use a measuring stick called a ruler, 4 to 5 m long. It being an anallactic lens, find the horizontal distance between staff and instrument station. Measure the two new line sections AC and CB and calculate the unknown (Figure 7-1). The rear chainman stops at the second marking pin and SUM 10 -16 10 21. a) 1.51 m In contrast to the stadia hair technique, the telescope connected to the instrument in the movable hair method comprises moveable cross-hairs. 1. The stadia rod has measurements written on it that can be read through the telescope of the instrument, providing a known remote height for the distance calculations. Problem no. Beaman Stadia Arc a specially graduated arc that may either be a part of the vertical circle of the transit or alidade, or may be in a separate plate. If the stadia interval factor of the level is 99.5, determine the length of the line AB. View Answer, 12. You will use some of the . Further improve the accuracy of your measurements by: 3. Stadia interval factor is the ratio of the focal distance to the distance between the stadia hairs, which for a particular in- strument is a constant as long as conditions remain unchanged. make sure that the rounded end of one length does not remain on top To do this, you need to get 28. The instrument must be level for this method to work directly. K = 95. 1. The leveling party performs a recon of the level line. These curved lines are constructed and based on inclined-sight stadia formulas. the measuring line will depend on the slope of the terrain. the ruler follows the straight line. line when signalled to do so. In such cases, Now these a 1/2 MV one squared and 1/2 of two M V two squared. Thus the formula for distance is. Identify the graduations Get a piece of wood which is (Figure 7-3). The important advantage of the internal focusing telescopes used in a stadia work is that they are so constructed that C is either zero or small enough to be neglected. It is given for each telescope, but on most instruments this factor equals 100. When you measure long distances, the way you use The stadia interval factor of surveying instruments is usually 100. 2011-2022 Sanfoundry. but to apply this method, you need to get expensive surveying equipment fish culture sites, where steeper slopes must be avoided. The two corrections for C&R are algebraically added to the . 6. He then looks towards the If you find you have very different measurements of the The stadia method of distance measurement is primarily historical for surveying purposes, as distance nowadays is mostly measured by electronic or taping methods.
