Abstract :
This study aims to examine the experimental of a deflection test instrument where this deflection phenomenon is often found in everyday life. In the test using a steel plate type ST37 which was tested at the end of the load free from the material and at a loading distance of 75 cm from the fulcrum and this time the test used a clamping support using 4 load variations, namely: 0.1 kg, 0.2 kg, 0.25 kg, and 0.5 kg. The results obtained from the experiment are: the maximum deflection that occurs at the loading position at the free end of the material is 0.1 kg = 1.72 mm, 0.2 kg = 3.31 mm, 0.25 kg = 4.61 mm and 0.5 kg = 9.21 mm. And the loading distance of 75 cm from the fulcrum is 0.1 kg = 0.57 mm, 0.2 kg = 2.68 mm, 0.25 kg = 4.33 mm and 0.5 kg = 8.48 mm. With the difference in deflection that occurs between the experimental and theoretical results in the loading position at the free end of material is 0.1 kg = 0.09 mm, 0.2 kg = 0.31 mm, 0.25 kg = 0.08 mm and 0.5 kg = 0.14 mm. while the deflection difference between experimental and theoretical results at a loading distance of 75 cm from the fulcrum is 0.1 kg = 0.57 mm, 0.2 kg = 0.39 mm, 0.25 kg = 1.48 mm and 0.5 kg = 2.76 mm.
