Physics

The moment arm of the biceps is approximately 2 cm from the axisof rotation of the elbow and the force vector representing thebiceps is approximately 115 degrees from the positive x-axis. Ifthe weight of the forearm and hand is 21 N and the center of massof the segment is 13 cm from the elbow joint:

  1. Calculate the muscle force needed to hold the arm in the staticposition
  2. Calculate the vertical component of the joint reactionforce
  3. Calculate the horizontal component of the joint reactionforce
  4. Calculate the orientation of the vector representing the jointreaction force.
