Pulley System Phone Cases - iPhone and Android

Description: A schematic illustrates a pulley system with two circular pulleys. Labelled elements include A, B, D, E, R1=BE, R2=CD, and D2=BC. Arrows indicate direction and tension forces. The text 'Keeping Tension Under Wraps!' is positioned at the bottom.

Description: A schematic diagram illustrating a pulley system, rendered with a chalk-like effect on a black background. The diagram features two circular pulleys labeled with points A and C. Lines represent the ropes and distances, labeled R1, R2, and d. Points D indicate the edge of the pulleys, and point E represents a weight suspended by a rope. The style resembles a physics or engineering textbook illustration.

Description: A hand-drawn diagram in chalk-style shows a pulley system. Two large wheels, labeled A and C, are connected by bands. Annotations include R1 and R2, indicating sizes or radii, and 'd' representing distance. Points labeled B, D, and E are also present, with arrows indicating direction of rotation or force.
