You are holding a 19.4 pound dumbbell in your hand. The dumbbell is being held 12.8 inches from your elbow (horizontal distance). Your forearm weighs 6.8 pounds, and the center of mass of of your forearm is 5.3 inches from your elbow, again measured horizontally. Assuming your biceps is the only elbow flexor muscle acting to counter the effects of the dumbbell and arm weight, and has a moment arm at the elbow of 2 inches, what is the force in your biceps required to balance the dumbbell and forearm weight? Include units in your answer (Ibs) Express your answer to the nearest 0.1 lbs
