Determine the critical load for a hollow-cylinder column. The column is pinned at both ends and is made from a SAE 1020 annealed steel alloy. The column has the following dimensions: - Length =800mm - Outer Diameter =20mm - Inner Diameter =4mm Use the figure shown on Slide \#3 of Lecture \#18 to determine the practical K value. The slenderness ratio, SR, for the cylinder given in the statement for Problem \#2 is: - Enter the answer as a number with no decimal places (Example: 123). The column constant, Cc, for the cylinder given in the statement for Problem \#2 is: - Enter the answer as a number with no decimal places (Example: 123). The critical load, Pcr, for the cylinder given in the statement for Problem \#2 is: - Enter the answer as a number with one decimal place using the unit of kN (Example: 12.3).
