Design and make a model of a machine to crush grain

A machine to crush grain will usually be powered by an electrical motor that provides rotational movement. You will not use an electrical motor in your model, but will rather turn the handle of a crank by hand. This rotational movement should be changed into a reciprocating movement so that the grain will be crushed, like hitting it with a hammer.

Olive oil extraction - Wikipedia

Olive oil extraction is the process of extracting the oil present in olive drupes, known as olive oil.Olive oil is produced in the mesocarp cells, and stored in a particular type of vacuole called a lipo vacuole, i.e., every cell contains a tiny olive oil droplet. Olive oil extraction is the process of separating the oil from the other fruit contents (vegetative extract liquid and solid material).
