Abstract: The development of a dual power air compressor system is the main goal of this work. The dual powered system provides a dependable and sustainable power source by combining solar power, grid supply, and a battery storage system. In order to maximize energy efficiency and save operating costs, the system is automated using sensors and Arduino micro-controllers to monitor and manage the systems’ performance. The compressors’ energy requirement was assessed and appropriate selection of solar panel capacity, battery capacity and inverter system to integrate with the grid power supply was conducted. Programmable codes were written in C/C++ language and tested using the proteus 8 software. Test results of the system show that the volumetric air flow rate of the system is 0.164 litres/second (i.e., 0.000164 m³/s) and within 255 seconds, 40 psi of air can be delivered to a 20 liters vessel. The system’s performance was seen to be satisfactory and is recommended for car tyre inflation.

Abstract: This study assesses the vibration characteristics of functionally graded rectangular plates resting on Winkler elastic foundation. Integral calculus has been applied to the beam analogy method for the evaluation of the non-dimensional frequency parameters of isotropic functionally graded (FG) rectangular plates resting on Winkler elastic foundation. The fundamental assumptions of linear, elastic, small-deflection theory of bending for thin plates due to Kirchhoff are taken into consideration. Using direct integration, characteristic orthogonal polynomials (COPs) shape function for plates clamped on two opposite edges and simply supported on two other opposite edges (SCSC) is formulated. The effect of aspect ratios on the natural frequency of the plate is examined. The findings of this study show that an increase in aspect ratio results in an increase frequency of the plate.  Adding an elastic foundation increases the non-dimensional frequency parameter of the plates. Like plates resting on Winkler foundation, an increase in aspect ratio, causes a corresponding increase in frequency for plates not subjected to the effect of Winkler elastic foundation. It is also observed that an increase in power law index decreases the frequency parameters of the plate. Results are in tandem with those in the literature.

Keywords: Free vibration, rectangular plate, Winkler foundation, functionally graded plate, analytical solution.
