Section 1.3: Stresses in the Members of a Structure - More information that just the internal force (i.e. F BC = 30N) must be found to see if the material is sufficient to hold a load. We also must investigate cross-sectional area of a rod (or other support) and its material o F BC actually represents the resultant of elementary forces distributed over the entire cross-sectional area, A, and the intensity of these distributed forces is equal to the force per unit, F

### 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.
