A uniform rod AB, 12 ft long, weighing 24 lb, is supported at end B by a flexible cord and weighted at end A with a 12 lb lead weight. The rod floats as shown, with one-half of its length submerged. The buoyant force on the lead weight can be neglected. a) Show in a diagram all of the forces acting on the rod. b) Find the tension in the cord. c) Find the total volume of the rod.
