A 72.0 kg weightlifter doing armraises holds a 7.50 kg weight.Her arm pivots around theelbow joint, starting 40.0° belowthe horizontal (Fig.).Biometric measurements haveshown that, together, the forearmsand the hands account for 6.00%of a person’s weight. Since theupper arm is held vertically, thebiceps muscle always acts verticallyand is attached to the bonesof the forearm 5.50 cm from theelbow joint. The center of mass of this person’s forearm–hand combinationis 16.0 cm from the elbow joint, along the bones of the forearm,and she holds the weight 38.0 cm from her elbow joint.
