Read the information, then answer the questions. An adult may read the instructions aloud. Show your working where asked.
Read before answering
Ideal mechanism card: The effort point on a model lever is moved closer to the pivot while the same load stays fixed. A lever turns around a pivot; pulleys redirect pulls and some arrangements change force; gears transmit rotation. Real friction and other losses limit ideal models. Use diagrams or safe small adult-approved models, not heavy lifting, climbing or pinching mechanisms.
