P3_4 Room on the Broom but can it still fly?

Abstract

In the children's picture book 'Room on the Broom,' the witch is joined by multiple animals on her broomstick during its journey \cite{brm}. By assuming the broom is in equilibrium when all the animals are on board, we found that the lift required to keep them in the air would be $850$$N$$\pm{30 N}$. The cauldron could be made of of titanium, which would be alloyed with denser materials and have liquid added to reach the required weight.
