• raise the pulley's wheel

• use a longer rope or cable

• clean and oil the pulley's axle

• lower the pulley's wheel

Answer 1

To make the pulley more efficient, the mechanics could **clean and oil the pulley's axle**. This reduces friction, allowing the pulley to operate more smoothly and effectively lift the engine.
