Question

Write a program to compute the diameter in centimeters of a steel, aluminum, and copper rod, which can withstand a particular compression load. The allowable compression stress of steel is 25,000 lbs/m2 , 15000 lbs/m2 for aluminum, and 20,000 lbs m2 for copper.

area of rod = compress load/ allowable compression stress

area = pr2 where diameter d = 2r

Input the compression load. Print the type of material. load, allowable stress, and diameter. Use format output with field with specifications that align the output.

Explanation / Answer

         //Varible declaration.
         double load,area,dia,radius;

         //Getting input.
           cout<<"Enter diameter of three rods:"<<endl;
              cin>>load;

         //calculation for diameter for Steel Rod.
            area=load/25000;
            radius=sqrt(area/PI);
               dia=radius*2;

        //calculation for diameter for alum Rod.
          area=load/15000;
          radius=sqrt(area/PI);
              dia=radius*2;
