Question

A tubular steel column CD supports horizontal cantilever arm ABC, as shown in the figure. Column CD has an outside diameter of 8.500 in. and a wall thickness of 0.385 in. The loads are $P_A = 400$ lb and $P_B = 600$ lb. Dimensions of the structure are $a = 5.1$ ft, $b = 7.1$ ft, and $c = 13.6$ ft. Determine the maximum compression stress at the base of column CD. Part 1 Determine the cross-sectional area and the area moment of inertia for column CD. $A =$ in.$^2$ $I_z =$ 17.41 in.$^4$ Part 2 Determine the internal axial force in column CD. Use the sign convention for internal axial forces. $F =$ lb
