In what type of system do all moving pulleys move toward the anchors at the same rate as each other and the load?

A simple pulley system is characterized by its straightforward mechanics, where all moving pulleys and the load travel toward the anchors simultaneously at the same rate. This uniform movement is due to the direct connection of the pulleys and the load, which allows for a direct and equal displacement relative to the anchors.

In contrast, more complex systems like compound mechanical advantage systems or complex pulley systems involve multiple pulleys combined together, which can alter the rate of movement between different components of the system. Essentially, these types of systems can redistribute the effort and change the speed or direction, resulting in different movement rates for various parts of the setup. Likewise, a 4:1 TMA system incorporates additional mechanics that create a mechanical advantage, impacting the movement relationship between the load and the anchor points.

Thus, the simple pulley system distinctly allows for all components to move cohesively and equally, making it foundational in understanding the dynamics of pulley systems.
