Lever systems 0.0 / 5 ? Physical EducationLever systemsGCSEOCR Created by: Bolt 775Created on: 19-11-17 08:30 What is mechanical advantage? First/second class levers provide mechanical advantage.This means they allow you to move a large output load with a smaller effort 1 of 18 What is the equation for mechanical advantage? Mechanical advantage=Load divided by Effort 2 of 18 In a first class lever,where is the fulcrum located? In the middle 3 of 18 In a second class lever,where is the fulcrum located? On the left side (on the side basically) 4 of 18 In a third class lever,where is the fulcrum located? On the left side (on the side basically) 5 of 18 Which part of the body takes the role of the fulcrum when a limb is acting as a lever? The joint 6 of 18 What axis goes with the frontal plane? The frontal axis 7 of 18 What axis goes with the sagittal plane? The transverse axis 8 of 18 What axis goes with the transverse plane? The longitudinal axis 9 of 18 What type of movement is created in the frontal plane? Abduction and adduction 10 of 18 What type of movement is created in the sagittal plane? Flexion and extension 11 of 18 What type of movement is created in the transverse plane? Rotation 12 of 18 What type of lever would you find located at the neck? A first class lever 13 of 18 Provide a sporting example of when you are working in the frontal plane about the frontal axis: A cartwheel in gymnastics as abduction and adduction occur 14 of 18 Provide a sporting example of when you are working in the sagittal plane about the transverse axis Running in cross country as flexion and extension occur at the knee joint 15 of 18 Provide a sporting example of when you are working in the transverse plane about the longitudinal axis: The execution of a shot in lacrosse,rotating the body at the hip joint 16 of 18 What is the load? The weight of the body parts that are moved or forces needed to lift,push or pull things.Eg; the weight of the ball 17 of 18 What is the effort? The working muscle is the effort,muscles provide effort to move loads 18 of 18
