Write a program to compute the diameter in centimeters of a steel rod, an aluminum rod, and a copper rod, which can withstand a particular compression load. The allowable compression stress of steel, aluminum, and copper is 25000 lbs/m2, 15000 25000 lbs/m2, and lbs/m2, respectively.
Area of rod = compression load / allowable compression stress
Area = pi r2 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.
