B.. Question 4. 121 pts] You try to design a workout system for yourself for one arm preacher curl to strengthen your biceps. The system you create has three wires as

shown in the figure below. Three wires are fixed to the floor. If you fix your elbow (G) to acts a pin, determine the force your biceps muscle is producing when you lift up the forearm to create a defromation of 1 cm in wire 3. Assume all the wires defrom vertically, have a diameter of 4 mm, and a Young's modulus of E-200 GPa. Assume the forearm acts as a rigid beam. Чтт meter of 4mm. 200 GPa 200x109 Pa A NAB NO Wire length: 30 cm Wire 1 -0.004 m Forearm: 40 cm B E 8 cm 8 cm D A NEF Wire 2 Wire 3 1 H 30° Nicep 90° 2 cm fo Gy Gy A. [5 pts] Draw a figure showing the forearm after deformation occurs. Then create an equation which relates the defromation in wire 3 (1 cm) to wires 1 and 2. B. [6 pts] Determine normal forces acting on wires 1, 2, and 3. C. [10 pts] Determine the bicep force and forces acting on the elbow joint. Hint: Draw a FBD of the when the forearm when its is horizontal.
