Homework Answers

Answer #1

the principal of levelling is to find difference of levels of two points with the instrument known as level.this can be achieved either by simple or differential levelling

SIMPLE LEVELLING

  1. it is the simplest operation in levelling, when it is required to find the difference in elevation between two points,both of which are visible from a single point of level
  2. the readings cane be obtained on a staff held successively upon these points
  3. the precise situation of the level is immaterial, but to elimnate the instrument error,the sight distance too the two staff positions should be kept as nearly as possible
  4. the level is set on a firm ground anywhere,not necssarily in the same vertical plane as that of two staff positions

DIFFERENTIAL LEVELLING

  1. determining the difference in elevation between two or more points without any regard to alignment of the points is called differential levelling.
  2. it is used when two points are at a large distance apart or when the difference in elevation between the ponts is large or some obstacle intervenes between the points.
  3. in such cases it becomes important and essential to set up a level in several positions and simple levelling procedure is employed in each of the successive stages. it is also called compound or continous levelling.
