Abstract: A spring scale was constructed by attaching several extension springs in series. The springs were acquired by disassembling a collection of staplers; however, these springs proved to be limited in their use, since they did not have a clearly defined elastic limit. The spring scale constructed has a k value of 7.05 ± 5.7x10-3 N/m. The measurement error was calculated to be equivalent to 0.34 grams. The scale is accurate to 1 gram and has a functional range from 60 grams to 450 grams.
