A three-compartment thin-walled box section has a constant wall thickness (fig 10.41). Find the values of the maximum shearing stresses in the various elements if the box is subjected to a twisting moment of 1,000,000 lb-in. How much larger would the stresses in the walls of the central compartment get if two cuts were made in the walls of the side compartments? (G=12 X 10^6 psi.)
