Read the wording for your board, then hide it and explain Force multiplication in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
The ratio of the effort arm to the load arm sets the force multiplication, so a long effort arm and short load arm turn a small force into a large one.
Because the larger piston area is larger, the output force is larger than the input force, though the smaller piston must move further.
