Before you begin, complete Table 1 below describing how you plan to raise the obelisk. Put your plan into action and record the results in the cells provided, paying careful attention to the calculations provided in the simulation. The goal of this activity is to understand the mechanical advantage which levers provide. Improve your plan in Table 2 and compare the results between the two tables. 1: Plan for Raising the Obelisk Object Mechanical Advantage Data Step Location Result Used Work = Force x Distance How did Lever Side Obelisk Side =, <, > obelisk W=FxD W=FxD move? 1 2 3 4 5 6 7 8 9 10 Table 2: Improved Plan for Raising the Obelisk Object Mechanical Advantage Data Step Location Result Used Work = Force x Distance How did Lever Side Obelisk Side =, <, > obelisk W=FxD W=FxD move? 1 2 3 4 5 6 7 8 9 10 Conclusion: Were you able to lift the obelisk? This is a virtual simulation to what the Egyptians had to deal with but they had to incorporate gravity into their solution as well. Used properly, levers can change the amount of effort needed to a fraction or what would be required without using this simple machine. The amount of force applied
