Question 31
The system is initially balanced. If one identical block is added on top of A, how many must be added on top of B? Preserve the original drawing. For a checked AI reconstruction, model equal-width uniform blocks with added loads acting at block centres and the pivot at the drawn boundary after the eighth block. Explain how this differs from the printed key’s assumed 8:2 lever arms. This is a paper model, not a practical balancing experiment.
