1. The problem statement, all variables and given/known data A lever is used to lift a heavy load. When a 50-N force pushes one end of the lever down 1.2 m, the load rises 0.2 m. Calculate the weight of the load. I really am not sure how to go about this. I realize work = fd but calculating the weight is where i get lost. Also, I had a question about: In the hydraulic machine shown, it is observed that, when the small piston is pushed down 10 cm, the large piston is raised 12 cm. If the small piston is pushed down with a force of 100 NB, what is the most force that the large piston could exert? Here I am completely lost.
