Labeled diagram of a double pulley system showing fixed and movable blocks, rope, load, force, and 4:1 advantage.

Labeled diagram of a double pulley system showing fixed and movable blocks, rope, load, force, and 4:1 advantage.
Pro

Prompt for image generation: A clean, technical illustration of a double pulley (double block and tackle) system used for lifting heavy loads. The image shows two pulley blocks: the upper block is fixed to a beam or hook, and the lower block is movable, attached to a load. A steel rope runs alternately between the pulleys, forming a classic double pulley system with four rope segments supporting the load. Elements to include: The load hanging from the movable block. Force arrows indicating the direction of applied force and load. Labels for parts: Fixed block, Movable block, Rope, Force, Load. Neutral light background (white or light gray). Rendered in a clean educational infographic style or realistic 3D engineering style with soft lighting, metallic textures, and subtle shadows. Optional: include a small inset diagram showing the mechanical advantage (4:1) of the double pulley system. See more
