Need help ASAP!!!!

please follow the instructions for programming this problem. I'm using C++ visual studios

Question 3 The maximum load that can be placed at the end of a symmetrical wooden beam, such as the rectangular beam shown in Figure A3, can be calculated as the following: s x I L is the maximum weight in lbs of the load placed on the beam. S is the stress in Ibs/in2 / is the beam's rectangular moment of inertia in units of in4. d is the distance in inches that the load is placed from the fixed end of the beam (the "moment arm"). c is one-half the height in inches of the symmetrical beam. Figure A3: Calculating a symmetrical wooden beam's maximum load For a 2" x 4" wooden beam, the rectangular moment of inertia is given by this formula: base xheight2x410.674 12 c-(4 in)-2 in a) Using this infomation, design, write, compile, and run a C+t program that computes the maximum load in lbs that can be placed at the end of an &-foot 2" *4" wooden beam so that the stress on the fixed end is 3000 Ibvin2 b) Use the program developed in Exercise 3a to determine the maximum load in Ibs that can be placed at the end of a 3" x 6h wooden beam so that the stress on the fixed end is 3000 Ibs/in
