Abstract: The purpose of this study is to give an idea to the Mechanical Engineering Students of the Lyceum of the Philippines University- Cavite on how the fatigue strength of a leaf spring is tested before it gets through the market. The researchers believe that the study will broaden the knowledge of mechanical engineering students about the behavior of a leaf spring on an actual service work. The researchers made a prototype that can demonstrate fatigue testing in the leaf spring and conducted the three sets of testing with three trials on each set to ensure the reliability of the equipment. The actual data gathered by setting the load and measuring the deflection of the using the prototype were compared to the theoretical data from the computation using the formulas from the book of Design of Machine Elements by Faires. After the actual data and the theoretical data were gathered, the researchers got a percentage of error of 9.09%, 9.09% and 4.04% for the three trials. The percentage error gathered after conducting three trials are acceptable for a testing apparatus that will be used for educational purposes. Hence, it can be concluded that the prototype is reliable, and it can be used as a laboratory apparatus for the Mechanical Engineering students of LPU-C.
