Problem 4-13 To correct a birth defect, the tibia of the leg is straightened using three wires that are attached through holes made in the bone and then to an external brace that is worn by the patient. Determine the moment of each wire force about joint B. Given: FI= 4 N F2 = 8 N F3=6N a = 0.2 m b= 0.35 m 02 = 15 deg d = 0.15 m e=20 mm f= 35 mm g= 15 mm 0/= 30 deg c = 0.25 m Problem 4-13 To correct a birth defect, the tibia of the leg is straightened using three wires that are attached through holes made in the bone and then to an external brace that is worn by the patient.
