You can look at your system of pulleys as a system that transforms gravitational potential energy into kinetic energy. In this view it is clear that the final VELOCITY depends only on the efficiency of the energy transformation. This efficiency does not depend directly on what axle you choose to drive. It depends mainly on how much friction is in your system. And this will increase with the number of pulleys. However, if you are interested in ACCELERATION then the answer is that you can make it as big as you want (neglecting friction) by choosing properly the system of pulleys (especially by choosing the radius of each pulley). But you cannot make it at the same time as big as you want AND for as long as you want it. So the final velocity will be a constant. These are only some thoughts to help you understand the system by looking at it from another (?) perspective. If you have other specific questions on this subject email me: email@example.com
