The safe load of a load bearing circular column of a specific material can be calculated by the slimness ratio (R) of the column. The slimness ration is defined as the ratio of the length of a column to the width (diameter) of a column (assuming both have the same units). When R is less than 120 the safe load (S) can be calculated by the formula s 16,750-0427 R2 otherwise the safe load can be calculated using the formula 18,000 1+ 1800 Prompt the user to enter the length and width of the column and use as simple if (single-branched) to confirm the user enters a valid value for the length and width. Next calculate R and S. Output the length, width, R and S (28 points)
