Allows you to move a large resistance with small a effort 8 of 13 What is the effort arm? The distance between the effort and the fulcrum 9 of 13 What is the resistance arm? The distance between resistance and the fulcrum 10 of 13 Mechanical advantage equation= Effort arm/resistance arm 11 of 13 When does a lever normally have a high mechanical advantage? When the effort arm is longer than the resistance arm 12 of 13 Where is the 3rd class lever system most commonly found? Joints in the human body 13 of 13
