Solve numerically the displacement(du) of an elementary length (dx) of the bar under a load P with the formula.
du/dx=P/EA
where E is young's modulus and A us cross sectional area
P=22KN, L=25.4cm , E=210Gpa , A=13E-0.1x

How do i get the dispacement of an elementary length dx. Is it like i need to integrate du for length 0 to 25.4cm? Suggestion are appreciated.
