O_TEXTBLOCK_TEXT When the <HL Topic=Fulcrum.tpc>FULCRUM</HL> is placed closest to the <HL Topic=Effort.tpc>EFFORT</HL>, the crate is propelled the highest, but not the farthest. Notice that the longest <HL Topic=Trajectory.tpc>TRAJECTORY</HL> is made by placing the <HL Topic=Fulcrum.tpc>FULCRUM</HL> in the middle. When the <HL Topic=Fulcrum.tpc>FULCRUM</HL> is placed nearest the <HL Topic=Resistance.tpc>RESISTANCE</HL>, the <HL Topic=Load.tpc>LOAD</HL> is propelled the shortest distance; this requires the least amount of <HL Topic=Force.tpc>FORCE</HL>, and is therefore easier.
