The moment arm of the biceps is approximately 2 cm from the axis of rotation of the elbow and the force vector representing the biceps is approximately 115 degrees from the positive x-axis. if the weight of the forearm and hand is 21 n and the center of mass of the segment is 13 cm from the elbow joint:
calculate the muscle force needed to hold the arm in the static position
calculate the vertical component of the joint reaction force
calculate the horizontal component of the joint reaction force
calculate the orientation of the vector representing the joint reaction force.
