A concrete cylinder sample has a diameter of 4 inches and a height of 6 inches. The maximum load carried by the sample after its failure is 275 KN. Determine the compressive strength of the sample in psi. (use 1lbf = 4.45 N, round-up your answer to the nearest whole number that is divisible by 5, no need for unit)
A composite column is formed by placing a steel bar, 20 mm in diameter and 200 mm long, inside an alloy cylinder of the same length whose internal and external diameters are 20 mm and 25 mm, respectively. The column is then subjected to an axial load of 50 kN. If E for steel is 200 OOO N/mm’ and E for the alloy is 70 000 N/mm’, calculate the stress in the cylinder and in the bar, the shortening of the column and the strain energy stored in the column.
