I am right now working on building a cheese press. But there is one important matter I do not know how to calculate.

This is a beam style press, relying on the leverage of a large wooden beam to achieve pressing pressure. The beam is fixed at one end, and the other end moves freely up and down. You press the cheese by placing a block under the beam and bringing it down to put pressure on the cheese in the mold.

What I need to know is how to calculate the actual poundage placed on the cheese based on the leverage of the beam. For this particular cheese I need to attain 1500 pounds of pressure.
