Analisis Perhitungan Gaya Berat pada Tongkat Gayung Lipat untuk Mengetahui Efektifitas Pengungkit Jenis Tiga

Abstract

Tongkat Gayung Lipat is a tool initiated by a PKM-KC team at the University of Education of Indonesia. The Tongkat Gayung Lipat is a tool that can help humans' outdoor activities. It has four main functions such as a mountain climbing tool, a container for taking water both far or near located, a flashlight in the stick handle serves as a lighting tool, and a knife in the stick handle serves cutting objects. Human needs when going on vacation and the limitations of the water dipper in tourist attractions are the reasons for making this tool. This tool was initiated to make it easier for people to do activities in the bathroom and do other activities outdoor (indoor and outdoor). Thus, to see the effectiveness of the tool, a trial was carried out by considering the load and human strength when lifting water. The calculation carried out using the third type of lever of physics laws approach which can provide a precise calculation of the effectiveness of objects. The analysis was carried out using the fourth lever type of physics law approach by calculated gravity, mass, and force. The result of the calculation was there is three comparisons of gravity. They are 23.6 N, 23.3 N, and 12.03 N. With these results, it is necessary to analyze the effectiveness of the Tongkat Gayung Lipat.
