An elbow is flexed to 90. The hand holds a bar on which a cable pulls with a 320 N force that acts at 40 to the vertical. This bar is held at a distance of 32cm from the elbow axis. Ata distance of 3 cm from the elbow joint (E), a biceps tendon force pulls straight up on the forearm, holding it in this static position. a) First, draw a fbd. Continue to add onto the fbd as you work through the problem b) then, find the horizontal and vertical components of force of the bar ) Now, solve for biceps force d) solve for the reaction force applied at the elbow joint. Provide both the magnitude and direction of the reaction force at the elbow joint
