Answer
The lever arrangement of he second class (second order) produces the most force. In the second class of levers the resistance (load /weight) is located between the effort (power) and the fulcrum--ERF.
Work Step by Step
The second class of levers produces the most force . In this class the load/weight. or resistance(R) is positioned between the effort (or power) and the fulcrum. In this arrangement some speed and range of motion are given up to obtain maximum force. An example of the second order of levers movement is displayed by standing on tip toe. In this example the ball of the foot is the fulcrum, the the weight of the body is the load or resistance (R), and the effort or power E) is exerted when the muscles of the calf (gastrocnemius and soleus muscles) contract.
