Write a program to compute the diameter in centimeters of a steel rod, an aluminum rod, and copper rod, which can withstand a particular compression load. The allowable compression stress of steel, aluminum, and copper is 25,000lbs/m^2, 15,000lbs/m^2, and 20,000lbs/m^2, respectively.
compression load
area of rod = ---------------------------------------
allowable compression stress
area = 3.1415r^2 where diameter d = 2r
Input the compression load. Print the type of material, load, allowable stress, and diameter. Use formatted output with field width specifications that align the output.
