Question
**Problem 1** A woman is lifting a 5 [kg] backpack in her right hand while leaving her class. Use the information given to: a) Draw and label the free body diagram of all forces on the elbow b) Calculate the force of the bicep using the sum of the moments The following information is given: - m = 2 [cm] - S = 5 [kg] - s = 26 [cm] - Beta = 4 [degrees] - Weight of the arm = 3 [kg] - Acceleration from gravity, g = 9.8 [m/s²] --- **Diagrams Explanation:** - **Figure 5-1**: This diagram illustrates the varying lever arm of the force vector \( M \) with different elbow angles. - **Figure 5-2**: This diagram shows the interaction between external force \( S \) and muscle force \( M \). It appears to be a schematic of the arm, showing the backpack at the hand, muscle force \( M \) at the bicep, and external force \( S \) with labels for distances \( m \) and \( s \) as well as the angle \( \beta \). These diagrams help visualize the mechanical forces and moments acting on the elbow joint when lifting the backpack.
