A graphical representation below shows that the shaft will not work under a certain load.Methods to analyze steel shafts used in motor vehicles demand for higher technical skills so as to perform intended function proving to be uneconomical. The material specific product design analysis uses incorporation of software to determine the life of shaft when operating under fatigue. Change in design and material of shaft can help in sustaining loads at various rates of revolution of motor engine. This is the only method to assure maximum life of the shaft even before it is put to test but it has to be appropriately replaced using other alternatives.If we let maximum load acting on the shaft to be Y MT and diameter to be Y mm and the span of the steel shaft be Z mm, then by our shaft model X= 12, Y=6.5 and Z=10 hence the load can be calculated in respect with time for the improved design of the steel shaft components. The composition of the new design EN19 shaft steel should consist of the following components in its modelThe modulus of the initial design will be calculated using Young modulus in the elastic linear portion. Modulus = whereby the new design aims at reducing the tensile stress hence an increase in the modulus value. The high the modulus the longer the shaft will work in the motorized host with a certain load acting on it. From the diagram below, it is observed at the strain induced on the shaft for the existing model has an average of on the Y-axis. The Finite Element Analysis below sows the results of for the existing design.Finite Element Analysis is carried over the proposed material and clearly mentioned in in figure 2. Theoretical value for the change of material (that is the EN24) for the existing design is approximated as .In addition, finite element analysis is carried out for the newer design and specified material. The integration of product design and material changes and further analysis revealed better results for the pertaining conditions of the shaft.The existing design and material of motor vehicle shaft have yielded a better life of 18 to 20 hours. This proves to be very uneconomical and the risk factor of the product for sustainable operation for stipulated period of operation is high. Once the load is reversed, both the measure and calculated results will remain constant from the point of reversing as once the shaft has experienced the strain, it can return to its original position due to
