Simple machines make work easier. most simple machines reduce the amount of effort force needed to move an object. in this wheel and axle system, the wheel and axle is used to pull a bucket up. a person turns the handle (p), using effort force. what if the bucket is really heavy and the wheel cannot be turned? how can the effort force be reduced so the bucket can be lifted?

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass
