In Fig. 14-38, a cube of edge length L = 0.600 m and mass 450 kg is suspended by a tope in an open tank of liquid of density 1030 kg/m 3 . Find (a) the magnitude of the total downward force on the lop of the cube from the liquid and the atmosphere, assuming atmospheric pressure is 1.00 atm, (b) the magnitude of the total upward force on the bottom of the cube, and (c) the tension in the rope. (d) Calculate the magnitude of the buoyant force on the cube using Archimedes’ principle. What relation exists among all these quantities? Figure 14-38 Problem 32.
