Many engineering machines and mechanical components are subjected to fluctuating stresses, taking place at relatively high frequencies and under these conditions failure is found to occur. This is called fatigue failure. And this led to the invention of a fatigue testing machine. In view of effective design that will not fail accidentally, this research is conceived. This testing machine will determine the strength of materials under the action of fatigue load. Specimens are subjected to repeated varying forces or fluctuating loading of specific magnitude while the no. of cycles are counted till the breakage of specimen and results are plotted.

Nowadays, Polymer composites are frequently used for engineering applications such as aerospace, automotive and marine industries. The present research is on evaluation of wear properties of epoxy resin composite fabricated using alumina (Al2O3) in 5wt% and Silicon Carbide (SiC) in 5-15 wt% in steps of 5 wt% as fillers for testing purpose. The tribological properties such as dry sliding wear characteristics have been evaluated by conducting wear tests using Pin-on-Disc wear testing setup for sliding speed (200/300/400 rpm) and sliding load (20/30/40 N). The wear properties are analyzed using Taguchi’s Design of Experiments and Analysis of Variance (ANOVA) techniques. From the statistical analysis it is found that the 15wt% of SiC is major factor influencing the wear resistance of the composite material. Finally regression analysis has been carried out to build regression model to predict the wear rate of the composite material under different sliding conditions.

The aim of our project is to generate free energy using flywheel. A mains motor of two horsepower capacity is used to drive a series of belt and pulley drive which form a gear-train and produces over twice rpm at the shaft of an alternator. The intriguing thing about this system is that greater electrical output power can be obtained from the output of the alternator than appears to be drawn from the input motor. This is done with the help of Flywheel. The gravity wheel or flywheel is coupled with the gear-train in order to produce more excess energy or free energy. Detail study is done with various parameters of flywheel to obtain the maximum free energy out of the system.
