select the correct answer. which of the following is an example of a class iii lever system? a. hammer claws b. wheelbarrow c. can opener d. bicep curl
Answer
Brief Explanations:
In a Class III lever system, the effort is between the fulcrum and the load. A bicep curl is an example where the bicep muscle (effort) is between the elbow (fulcrum) and the weight in the hand (load). Hammer claws are Class I levers, wheelbarrows are Class II levers, and can - openers are a combination of levers but not a typical Class III example.
Answer:
D. Bicep curl
