The main purpose of this study is to construct load applied power generator and test the results. In this study, the principle used is the conversion of the forced mechanical energy into electrical energy. The mechanism carries main components like upper plate supported with two springs, rack and pinion and D.C generator. Rack and pinion mechanism is used to change linear motion of rack gear into rotational motion of pinion gear. The power generated can be stored by means of battery and can be used for activating the connected LED. This model can be installed in bus stations, airports and highways where the load to be applied on the upper plate is easily available. In this study, by using the kinematic relationship between linear velocities of large gear (95 teeth) and small gear (20 teeth), the rotational speed of output shaft is found to be 570 rpm. Theoretically, the large gear and small gear mesh at the pressure angle of 17.59°. Input shaft diameter is estimated by using maximum shear stress theory and maximum normal stress theory. From two results, larger value is selected, the estimated diameter of rotating shaft is 20 mm. Theoretical effective stress, Von-Mises stress, is 271.54 MPa and effective strain is 1.83×10-9. The maximum output electrical energy is found to be 2 W.
