When a person stands on their tiptoes, the ball of the foot acts as the fulcrum, the body weight acts as the load in the middle, and the calf muscles pull upward at the heel. Which class of lever does this body movement represent?
  1. Class I Lever
  2. Class II Lever
  3. Class III Lever
  4. Complex Lever

Solution

In a Class II lever, the load is situated between the fulcrum and the effort. Standing on tiptoes places the body load between the pivot at the toes and the muscle effort at the heel.
