* ABSTRACT
This experiment is conducted to calculate the transverse bending deflection of the tie bar and compare it to the theoretical values. There are two theoretical formulae that are given in this experiment which are simple theory method and exact formula. By comparing the values, the adequate method to calculate the deflection of tie bar can be found. besides, the 10% of error is accepted for simple theory method in order it to become adequate. * 1.0 Experiment design

* * 1.1 Method * The method uses in this experiment by measuring the gauge at the centre of the eccentric tie apparatus. It will give the number of divisions and times it with 0.01 to get the measurement as one division is equal to 0.01 mm. The product is the deflection of the tie bar, Δ. After that, the Δ also will be calculated using the simplified theory formula and exact formula. The compare the results that been obtained in the form of graph. * * * * *
