Transcribed Image Text:**Transcription:**
**Given:**
- R = 50 lbs
- Length FE = 0.75 inch
- Length FR = 12 inches
**Tasks:**
- Calculate E (lbs)
- Calculate MA
**Diagram Explanation:**
The diagram illustrates a lever system in the form of a bent arm holding a weight. Key elements include:
- **R (Resistance Force):** A downward force of 50 lbs representing the weight being held in the hand.
- **E (Effort Force):** The force exerted by the muscle to balance the resistance.
- **Length FE:** The distance from the elbow (fulcrum) to where the muscle applies the effort (0.75 inch).
- **Length FR:** The distance from the elbow (fulcrum) to where the resistance is applied (12 inches).
**Objective:**
- Calculate the effort force (E) needed to balance the resistance using the formula for levers: \( MA = \frac{FR}{FE} \)
- Calculate Mechanical Advantage (MA) using the given lengths.
This setup demonstrates how to apply principles of levers to understand mechanical advantage and the forces in play within the human arm.
