The final accepted bit is checked from packet, work, load, and waste sources. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.
highlighted = computed this step
The load gate must also accept
The load source says 6 newtons equals the maximum payable force, so its accepted bit is 1.
6=6⇒1
The final bit accepts only the closed cycle
Packet input 60, useful work 36, waste 24, and load acceptance all agree, so the final accepted bit is 1.
