Model of a Differential Pulley 1860

Adriaan Rosel's "Model of a Differential Pulley" is a detailed 1860 model of a pulley system, crafted in bronze and featuring chains. This small-scale, meticulously crafted model showcases the working mechanism of a differential pulley, a simple machine that utilizes two pulleys of differing diameters to amplify force for lifting heavy objects. This detailed work demonstrates Rosel's interest in capturing the intricate complexities of mechanical engineering through art, a testament to the interplay between science and art in the 19th century.
