long onto the deck of a ship. He exerts a 650.0 N force parallel to the ramp. What is the mechanical advantage of the ramp? What is the efficiency of the ramp? Your response should include all of your work and a free-body diagram. Answer: 650 N is mvoed through a distance of 5m. The result is 100*9.8 N is moved up thrugh a distance of 3m. Mechnical advanatage is 100*9.8 / 650 = 1.5. The maximum mechanical advanatage can be 5m / 3 m = 1.66 Efficiency = 1.5 / 1.66 = 0.90 = 90% (7 points)
