A simple machine that would help Trisha move shingles from the ground to the roof is a pulley. A pulley can be used to lift heavy loads, like bundles of shingles, by allowing her to pull down on a rope or chain, effectively raising the shingles up to the roof with less effort. Another option could be a ramp (inclined plane) if she is using a system to push or roll the shingles up instead of lifting them.
Trisha works for a roofing company and needs to move shingles from the ground to the roof.
