Problem 6 A muscle at point A in the forearm is used to pull on three separate tendons in the hand (shown in diagram). The tendons all originate at A and attach at points B, C and D as shown in the diagram. The following are the coordinate points (x, y, z) for the tendon attachment point measured from A: bl B: (0.1, -2, -20) cm C: (0.2, -1, -19) cm D: (v0.3, 3.5, -20) cm What is a tendon? What is meant by a tendon \"origination" and "insertion or attachment\"? Cite your source (don't just give me a website). Note: make sure you're looking at a source that's talking about tendons, not muscles. A force of IZDON is applied at the wrist by the muscle attached at A which causes all three fingers to move at the same time. Assume that once the tendons stop moving, the force from the muscle is enough to balance the system of the three ngers (equilibrium at point A). Write the equilibrium equations for the system at point A. Previous testing has shown that the tendon-bone insertion sites in the fingers (B-D) fail when 750M is generated in a finger tendon. Do any of the tendon-bone insertion sites fail under this load? Show all work to justify your answer. Note that the z axis is aligned with the muscle in the forearm. All coordinates given are based on this coordinate system
