Honey separator

One of our users, Christian, wondered about the centripetal (or centrifugal, depending on your reference system) force in his honey separator. He basically has got a centrifuge for his honeycombs which extracts the honey using this force, but unlike our experiment using a salad spinner, he was unable to measure the acceleration directly because it exceeds the range of the sensors in his smartphone. So, instead he attached his phone to the crank of the centrifuge and created his own phyphox experiment, which uses the gyroscope to determine the rotation speed of the crank. From this, his experiment then derives the speed of the centrifuge itself and all the forces involved, taking into account the transmission of the crank as well as the radius at which the honeycombs are placed within the centrifuge. If you are interested in this, here is a link to directly open his exeriment in phyphox and a link to download his phyphox file defining the experiment.

Thanks to Christian for sharing this unusual application with us.
