W'F shape. 8.Cl 8.61 Let us assume that the shear V and the bending moment M have been detemlined in a given section of a rolled-steel beam. Write a computer program to calculate in that section, from the data available in Appendix C, (a) the maximum normal stress 0,", (b) the principal stress on,“ at the junction of a flange and the web. Use this program to solve parts a and b of the following problems: (1) Prob. 8.1(Use V=400kNandM= IOOkN-m) (2) Prob. 8.2 (Use V = 200 [N and M = IOOkN ‘- m) (3) Prob. 8.3 (Use V = 320 kips and M = 32 X 103 kip ' in.)

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
