The following figure represents a bicep curl maneuver where the center of mass (CoM) of a 23 kg dumbbell is 0.29 m from the elbow joint (pivot). The mass of the arm is 5 kg and acts 0.17 m from the elbow joint, and the biceps tendon acts at a distance of 0.01 m from the elbow joint. A)The triceps produces a negligible force and the arm is at an angle of 15 degrees above the horizon. The given distances from the joint are the distances along the line that is 15 degrees above the horizon as shown in the figure. What magnitude of force in newtons (N) must the biceps muscle produce to hold the 23 kg mass in place (static equilibrium) b)
