Must show all your work and drawings similar to what I gave you all in the last lecture notes! If the humeroulnar joint is flexed at 25 and the biceps brachii has an angle of pull of 32 with a generating force of 350N at the radius. The muscle is attachment to the bone is 1.5 cm from the center of the humeroulnar joint. 1. How large is the component of this force that pulls the radius toward the humeroulnar joint? 2. Is this component a stabilizer or destabilizer? 3. How large is the component of this force that pulls perpendicular to the radius? 4. How much torque is produced at the humeroulnar joint by the biceps brachii? If the humeroulnar joint is flexed at 100 and the biceps brachii has an angle of pull of 145 with a generating force of 200N at the radius. The muscle is attachment to the bone is 0.50 cm from the center of the humeroulnar joint. 5. How large is the component of this force that pulls the radius toward the humeroulnar joint? 6. Is this component a stabilizing or destabilizing? 7. How large is the component of this force that pulls perpendicular
