● Weight of forearm = 1.6kg ● Center of mass (COM) = 18cm from elbow ● Weight of load held: 15 kg ● Forearm length: 36cm a) What is the force of the forearm (in N)? b) In what direction is the force of the force of the forearm? Positive or negative c) Demonstrate how you found the force of the forearm d) What is the force of the load (in N)? e) In what direction is the force of the load? F) Demonstrate how you found the force of the load

The image depicts a biomechanical diagram of a human forearm applying force. It shows a side view with various components labeled for reference:

- **R Elbow**: The reaction force exerted at the elbow joint.
- **M Elbow**: The moment at the elbow.
- A hand gripping an object is shown at the right end of the forearm.
- The weight of the forearm and hand is represented as a downward force labeled $ W_{\text{Forearm and Hand}} = 16 \, \text{N} $.
- Two distances are noted:
- From the elbow to the center of mass of the forearm and hand: $ 18 \, \text{cm} $
- From the elbow to the hand: $ 36 \, \text{cm} $

The diagram visually represents the mechanics involved, including forces and moments acting on the forearm when holding an object. This helps in understanding the distribution of forces and analyzing the mechanical equilibrium of the arm.

Expert Solution

Step 1: Write the given data and what is to find
