Abstract This experiment is conducted to measure the transverse bending deflection of the tie bar and at the same time comparing it to the theoretical values. The two theoretical formulae to get the central deflection in this experiment are simple theory method and exact formula. By comparing these formulas to the experimental formula, the most suitable method to measure the central of deflection could be obtained. This experiment is then continued by measuring the adequateness of the Simple Theory by allowing a 10% error. In overall, the experimental value is one of the best method to find the central deflection of the tie bar. 1.0 Introduction The structure and the design of a mechanism sometimes counteract the line of pull by having a tension force. This means that the tension member has to carry a both tension and bending with an increase eccentricity of the load at the back. In the experiment, the load line is outside the middle third of a square tie bar. This causes the bending moment takes over and there will be a bending deflection. A mathematical solution can be found from the eccentric loaded tie by using some differential equations. In this experiment, the students to have the opportunity to study on how to measure the transverse bending deflection of the tie bar and comparing it with the theoretical values. There are two theoretical values that are used to get the central deflection of the tie bar which are the simplified formulae and the exact formulae. One of the approximate solutions that could be obtained is by regarding the tie bar as a beam with equal and opposite couples applied which then produces circular bending. A
