Headings Tele subtitles Paragraph FALL 2019 ENGR 200 P2: STRESS STRAIN TESTING (basic program development, logarithms) POINTS: 40 DUE: September 24, 2019. by 11:59 pm. US Central Time RES INTRODUCTION: During tension testing on material samples, a specimen is pulled in a machine The machine records the force E applied to the specimen and the length of a section of the specimen. This data can be used to plota stress- strain d rama of the material, which can be used to predict how the material will behave in real world conditions under specific forces. The true stress of a material is defined by the following equation FEL SUL . .. prog shes L Where stress (p) F fore applied to the specimen (1) L-length of a section of the specimen (sometimes calledupe length (m) As initial cross-sectional wres of the specimen (!) a l length of a section of the specimen (sometimes called initial pupe length)() The true strain of a material is defined by the following equation: - in Sah Sube progr L strin ( less - sometimes expressed as ) ength of a section of the specimen Caugelegt) (in) L- al length of a section of the specimen C l oth (in) 12 ASSIGNMENT: Write a program that will allow the we to enter the force applied to the sample, the elemth of the sample, the initial cross sectional area of the sample and the initial gauge length of the sample. Once the user enters the initial values, the program will compute the tre stress and trust of the sample You program otput will look like the sllustration shown on page 2 Use your PC's cursor to determine the hoitaa vertical spacing for the output format

There is a specific input method as well that is needed to be used. If possible could you help with the following criteria? It is posted below.

Code

#include<stdio.h>
#include<math.h>

int main()
{
   /* Declare variables */
   float F,L,A0,L0;
   float stress,strain;

   /* Print headings */
   printf("********************************************");
   printf("\n\tSIMPLE TRUE STRESS AND STRAIN\n\n");
  
   /* Input values */
   printf("Enter Force in pound :");
   scanf("%f",&F);

   scanf("%f",&L);
   printf("Enter Initial x-sectional area in in^2:");
   scanf("%f",&A0);
   printf("Enter Initial Gauge Length in Inches :");
   scanf("%f",&L0);

   /* Compute */
   stress=(F*L)/(L0*A0);
   strain=log(L/L0);
