How to Use Optical Square and Open Cross Staff

Offsets can be accurately set up, particularly long offsets, by use of optical instruments like cross staff or optical square etc.    a) Cross Staff:             Two pairs of vertical slits, mounted orthogonally on a pole staff constitutes a simple instrument for setting out normal offsets as depicted in Figure. Each pair of slits can form a line of sight. It is fixed on a stand. Two persons are required to operate cross staff. Use of cross staff: 1. To find a foot of perpendicular on chain line 2. To set out the perpendicular from a given point.   b) Optical Square: It may be noted that at least two surveyor’s are required to set normal offsets while using cross staff. This disadvantage can be overcome if optical square is used for this purpose as only single surveyor can perform this task. Principle of optical square:   The angle between the first incident ray and the final reflected ray is twice that of t...

Direct and Indirect Ranging

  Measurement of distances with Chain and Tape on ground with Direct and Indirect Ranging   Principle of Chain Surveying:            The principle of chain surveying is derived from principle of triangulation. The area to be surveyed is divided into a number of triangles and the sides of the triangle are measured in the field. To get good results in plotting, the framework should consist of triangles which are as nearly equilateral as possible. Preferably all the sides of a triangle should be nearly equal having each angle nearly 60 o  to ensure minimum distortion due to errors in measurements of sides and plotting.   Theory:        The process of establishing intermediate point on a straight line between two end points is known as  ranging . Ranging must be done before a survey line is chained. It may be necessary to establish a number of intermediate points prior to chaining w...

Rolled Steel Sections

  Rolled Steel Sections       Structural steel sections are hot rolled into different shapes and sizes to form the different sections. Cross section and size are governed by functional requirements, dimensional and weight capacity of rolling mills, arrangement of material for optimum structural efficiency. In a rolling mill molten steel from furnace is poured into continuous casting system where steel solidifies but it is not allowed to cool completely. Then hot steel passes through series of rollers. Such series of rollers squeezes steel into desired cross sectional shape. If the load to be resisted is small single rolled steel sections are used. If the single section is insufficient, single sections are combined or built up with angles/ channels/ I sections with or without cover plates and /or laced, providing sufficient resistance to heavy loads. Most commonly used hot rolled steel shapes are as follows: 1. Rolled Steel I -Sections 2. Rolled Steel C...
