Question:
1 Draw the FBD for flexion of the humeroulnar joint. a. Assume the person is facing the right side of the page and the movement is an angular arc moving to the right of the page. b. The person is standing and the starting position is 30 degrees from the vertical plane. Assume the upper arm is held straight throughout the ROM.
2 Label all force vectors, angle, and distances.
3 Calculate the force exerted by the biceps brachia muscle on the ulna during 45 degrees of flexion toward horizontal, given the following data and formula: Distance from humeroulnar joint to biceps brachii insertion Radius/ulna center of mass length Distance from humeroulnar joint to wrist Mass of radius/ulna Mass of weight Angle of bicep brachii degrees
