Pulleys are used in multiple classes of all levels. In early education, they are used to learn about simple machines, and in higher education, they can help demonstrate work, force, and weight distribution. While pulleys have a relatively low cost compared to other resources, they are important for most, if not all, schools in one of their various classroom settings. Depending on the load placed on the system, these pulleys can completely eliminate the need to purchase costly versions, as they have an almost identical function. Additionally, these allow for customizability with the various sizes and placement positions.
