I did a practice question that said a mass is on a board which pivots at one end and at the other end, a pulley is attached to the board. So 2 machines are acting on the mass. Then the solution said that both the lever and pulley system reduce the force by a factor of 2 each.
Even if you don't understand the setup of the question, my question is: is it just something we need to know that every machine decreases work by a factor of 2, or was there something in this problem that i missed that...
Do all machines decrease force by a factor of 2?
