a pulley is not a complex machine. it is a small wheel with a groove around it. a rope is passed over it to pull the load easily. so it is a simple machine

When working in your yard or garden, do you constantly have a problem with your wheelbarrow tipping over? The key to keeping your wheelbarrow from tipping is to lock your elbows in a straight position when picking up the wheelbarrow. Lift with your knees and not your back to avoid your load from tipping.
