Write a program in C 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 25,000lbs/m2, 15,000lbs/m2, and 20,000lbs/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.
