This research work focused on the design, and optimization of the concrete mixture using factorial analysis. Data were collected for the concrete mixture proportion to observe the ratio of the mixture content. Factorial design analyses were used to design the concrete mixture. It was also used to optimize the concrete mixture of the variables. The results were discussed and were also recommended for concrete mixture.
The study aimed to construct a device that will be helpful for every automotive mechanic in terms of bleeding automobiles brakes and clutch system. The Hydraulic Brake and Clutch Bleeder was fabricated from locally available materials making it more cost effective. The device is operated by one person that simplifies the task of bleeding the system, and with less chance for the wear and tear of parts that may occur during the process. The device is users friendly with fewer operation procedures.
The Hydraulic Brake and Clutch Bleeder was evaluated by the experts and automotive technician from the various automotive shop and also persons who have knowledge about automobile. It was evaluated based on three (3) criteria such as functionality, efficiency and effectiveness, and safety. The Hydraulic Brake and Clutch Bleeder was rated by 30 respondents from the academe and industry. It gained an overall rating 4.55 which means that the device is highly acceptable.
