Step 1
The cross-sectional area of the tube is the area of the outer square minus the area of the inner square. The outer square has sides of 75 mm + 12 mm + 12 mm = 99 mm. The inner square has sides of 75 mm. Therefore, the cross-sectional area of the tube is (99 mm)^2 Show more…

EXAMPLE 4.3 Rigid beam AB rests on the two short posts shown in Fig 4-Ta. AC is made of steel and has a diameter of 20 mm, and BD is made of aluminum and has a diameter of 40 mm. Determine the displacement of point F on AB if a vertical load of 90 kN is applied over this point. Take Est = 200 GPa, Eal = 70 GPa, 90 kN, 200 mm, 400 mm, 300 mm.
