Problem Description The maximum stress resulting from a force acting on a cantilever beam (see Figure ) can be formulated as follows: P My L w It where, = maximum bending stress [Pa] or [MPa] M = maximum bending moment [N.m] y = distance from neutral axis to outer surface where maximum stress occurs [m] 1 = moment of inertia [mt] The value of M, y and I can be obtained from the following formula: M = P.L ; y = t/2 ; 1 - 12 For a simply supported beam with center load, the maximum stress is given by: P L/2 L/2 w - My 1 t with, M- PL 4 ; y=t/2 ; 1 - wr 12 THE PROBLEM You need to produce a menu driven software written in C which allow the user to: a. Choose to analyse the maximum bending stress of a cantilever or a simply supported beam. On selection, user needs to enter the parameters; P, L, w and t. b. Display the calculated M, I and maximum stress result on-screen c. Save the calculated result into a *.txt file d. Programmer information e. END the program
