Lifting With A Pulley

First my class saw Ruby using scales with a metal lathe plate hanging on the bottom of the scales then her face turned red.

Suddenly Mrs Bryant said, “You can put it down now”.

Then Ruby had a turn with the pulley. Mrs Bryant asked, “Is that easier?” Ruby replied, “Yes”.

Suddenly Mrs Bryant told me to have a go.                   David

Pulleys make it easier to lift things into the air. They are useful for lifting weights and heavy things. Today in class we were lifting a metal lathe plate with scales and a rope with a pulley to see which one was harder to lift. We found that it was harder with the scales. To get the lathe plate the same height as it was with the scales you need to pull the rope two times higher. Lawson

Lifting with the pulley is a lot easier than lifting with the scales. Because the scales just tell you the weight and the pulley is helping you to lift what ever you’re lifting. When you’re lifting the pulley lift it two times higher than the weight moves.                                                                Aria

Pulleys make it easier to pull things up. You have to pull it two times higher. Jonty
