Transcribed Image Text:A person is doing exercise by pulling a rubber belt. When the person is
keeping the posture shown in the figure, the arms form an "L" shape. Points A and B
correspond to the shoulder and elbow joints, respectively. Assume that the rubber belt
can exert a downward force with magnitude F on the arm at point C. If the lengths of
the upper arm and lower arm are a = 26 cm and b
32 cm, respectively, and the
magnitude of the applied force is F
500 N:
Determine the magnitudes and directions of moments developed at the lower and upper
arms by F. Please use both the scaler method and vector product method.
