Just as in the tensile stress experiment (Figure 6), the components of the stress forces \(d \mathbf{F}\), normal to the rod length, have to equal zero on the surface of the rod.

Where does the formula for bending of a rod come from?

WebA slender rod (mass m, length L) has a solid circular cross section with radius R (<< L). It is pinned at one end and held horizontally by a string. The string is then cut allowing the rod to rotate about the pin support in a vertical plane. At the instant the string is cut, find an expression for the maximum stress in the rod. WebArea Moment of Inertia. The second moment of area, more commonly known as the moment of inertia, I, of a cross section is an indication of a structural member's ability to resist bending. (Note 1) I x and I y are the moments of inertia about the x- and y- axes, respectively, and are calculated by: I x = ∫ y 2 dA. I y = ∫ x 2 dA. boat mover crossword clue
