Cao Chong's method of calling an elephant is really unique. Can you think of other ways to weigh an elephant?

You can make an elephant weighing seesaw, which probably uses the principle of lever to make the elephant stand at one end and use objects at the other. When the weight of the items is the same as that of the elephant, add up the weights of the items and calculate the weight of the elephant.

You can also tie elephants with steel cables, and then tie a big basket at the other end of the cable with the pulley of the crane, and put heavy objects in the basket. When the weight is equal, it will be balanced, and the weight of the elephant can be calculated by calculating the weight.
