Write a main function, and the following functions to compute the stress and strain oa a steel rod(d) (in inches) and length(l) in inches subject to the compression load(p) of 10,000 to 1,000,000 pounds in increments of 100,000 pounds. the modulus of elasticity (e) for steel is 30 x 10^6.
function to compute the stress formula:
stress f = p/a

where a =πd2/4.0

a function to compute the strain from the formulas:

elongated or shortened length:

δ l = fl/e

strain e = δ l/l = f/e

a function to output the stress and strain at different loads of p

the function should call each other as main(top), calulate stress(1), calculate strain (2) and output (3)

also need a flow diagram to accompany program
