Errors in surveying

An error in surveying is defined as the difference between two or more values of an identical quantity. However, the estimates are never accurate and there will always be a degree of variability regardless of the research tool or method used. These differences are known as errors that need to be reduced or eliminated to maintain certain levels of accuracy. Even if you carefully follow the prescribed test procedures, the considerations may contain errors.

Introduction Structural analysis is important for designing all type of structure including truss structure. There are several method to analyse truss structure. Therefore, student should be able to analyse the truss structure with appropriate method. This assignment is given to student to evaluate the ability of the student in solving the complex problem involving truss structure as shown in Figure 1 below. B 6m 88) O 20kN By using an appropriate method, i) 6m 20kN/m D 30KN Figure 1 6m H 20KN 6m LL G Figure 1 above shows a truss structure, which is supported at A and G. The truss is design to support a uniform load 20kN/m from C to E as shown in the figure. Given the elastic modulus, E=200GPa, and the cross-sectional area for member AJ, JI, IH, and HG is equal to 500mm² while other members is equal to 250mm². Based on the details given, solve the following task to analyse the truss structure. Task 1 8m Describe the determinacy and stability of the truss structure. Your answer must be…
