Learning Goal: To practice Problem-Solving Strategy 8.1 Static equilibrium problems.When you lift an object by moving only your forearm, the main lifting muscle in your arm is the biceps. Suppose the mass of a forearm is 1.00 . If the biceps is connected to the forearm a distance = 3.50 from the elbow, how much force must the biceps exert to hold a 500 ball at the end of the forearm at distance = 30.0 from the elbow, with the forearm parallel to the floor? How much force must the elbow exert?I need to know the horizontal distance between the elbow and the point where the weight of the forearm acts. What is the formula for that?
