Determine the ratio of the areas of the rods so that the slab will remain level. Figure P-215 Steel E - 29 x 10 psi Aluminum E - 10 x 10 psi L- 4 ft L-6R Total Weight = w 3 ft 6 ft The value of the load P at the aluminum 0.33 W b. 0.67 W с. W d. none of the above The ratio between the internal reactions of the aluminum and the steel 2.03 b. 0.49 c. 0.67 d. none of the above The ratio between area of steel and area of the aluminun 0.867 b. 0.409 c. 0.258 d. none of these If the value of W is limited to 1500 lb, which of the statements is true? The maximum load the steel can carry is greater than of the aluminum The maximum load the aluminum can carry is greater than of the stell The sum of loads at the steel and the aluminum is twice the value of steel The deformation developed at the steel is greater than that of aluminum If the cross-sectional area of the steel and of the aluminum is doubled, which of the following is true? a. The deformation in each material remains constant b. The ratio between area of steel and area of the aluminum remains the same c. The internal reaction at the steel and the aluminum changes d. Either the steel or the aluminum attains failure
