On the other end hangs a heavy counterweight, so the motor only has to lift the difference, a bit like two children balancing on a seesaw.

Who acts: heavy counterweight, motor, two children · What happens: hang, have, lift, balance · To what, where: other end, difference, seesaw

The tree: Mova annot: Rust (en) → Haiku 5.5 (medium, Batches API) patches; gates UD 2.18; agreed by treeagree rules (Stanza, Trankit, spaCy trf): R6-punct-agree ×1. The frames are read from the tree by Mova's frames reader (prag) when this page is built, the lesson read in order, so a pronoun may be resolved from an earlier sentence.
