Extension to practical applications 2. The human forearm can be modeled as a simple lever. Indicate on the diagram with proportional arrows, the direction of the load and effort forces on the Radius bone at their points of action. Ignore the weight of the bones and triceps. Draw a fulcrum for the Radius bone. How will the effort force supplied by the bicep compare to the load force? Estimate the ratio of effort force / load force using the distances in the diagram and your collected data above.
