233. Questions? –What was the advantage in newtons to use a fixed pulley rather than no pulley at all? –There was no Mechanical Advantage (MA) when using the fixed pulley. It was easier because you didn’t have to bend down. Copyright © 2010 Ryan P. Murphy

235. Questions? –What was the advantage in newtons to use a combined pulley over a fixed pulley? Copyright © 2010 Ryan P. Murphy

236. Questions? –What was the advantage in newtons to use a combined pulley over a fixed pulley? –The combined pulley required less force (2 newtons) to lift the load. The Mechanical Advantage was 2 newtons. Copyright © 2010 Ryan P. Murphy

238. Questions? –What was the advantage in newtons to use a combined pulley (4) over a combined pulley (2)? Copyright © 2010 Ryan P. Murphy

239. Questions? –What was the advantage in newtons to use a combined pulley (4) over a combined pulley (2)? –The (MA) was 4. It only took 1 newton to lift the load compared 3 newtons with the combined 2 pulley, and 5 newtons with no pulley at all. Copyright © 2010 Ryan P. Murphy

241. Questions? –Did a moveable pulley allow you to move the load with minimal effort? Copyright © 2010 Ryan P. Murphy

242. Questions? –Did a moveable pulley allow you to move the load with minimal effort? –The pulley moved along the rope very easily. We were able to move the load easily once it was lifted. The pulley rolled down the rope because of it’s potential energy. Not very good for lifting. Copyright © 2010 Ryan P. Murphy
