A cook holds a 1.80-kg carton of milk at arm's length. What force FB must be exerted by the biceps muscle? An arm is extending horizontally to the left with a cutout that shows muscles in the upper arm. A carton of milk is in the hand, and an arrow labeled vector Fg points directly downward. A point on the person's forearm lies a horizontal distance of 25.0 cm to the right of the milk and a horizontal distance of 8.00 cm to the left of the elbow. An arrow labeled vector FB points from this point up and to the right at an angle of 75.0° from the vertical.
