Levers, Pulleys and Inclined Planes: a 3D model for Class 9–10 Science, covering Work = force × distance moved in the direction of the force; raising 10 N by 1 m takes 10 J., Lever balance: effort × effort arm = load × load arm, with each arm measured at right angles to its force., For vertical forces the ratio of the arms stays the same as the lever tilts…, A fixed pulley has one supporting strand: it changes the direction of the force but the effort is still 10 N…, An ideal pulley needs effort W ÷ n for n supporting strands; with n = 2, lifting 1 m pulls 2 m of rope..
