Consider the general problem of a bar made from m segments, each having a constant cross-sectional area Am and length Lm. If there are n loads on the bar as shown, write a computer program that can be used to determine the average normal stress at any specified location x. Show an application of the program using the values L₁ = 4 ft, d₁ = 2 ft , P₁ = 400 lb, A₁ = 3 in², L₂ = 2ft , d₂ = 6 ft, P₂ = −300 lb, A₂ = 1 in².
