Another way to prevent a frame from skewing is to triangulate it twice, to make a cross. One brace goes from the top left to the bottom right of the rectangle. The other brace goes from the top right to the bottom left of the rectangle. case A case B Figure 32: Cross-bracing a frame This is called cross-bracing. It is a special kind of triangulation. With cross-bracing the frame does not skew when forces are applied as in case A or case B. 3. Compare the frame design in Figure 31 with the one in Figure 32. (a) Can you use steel cables instead of beams for the braces in both of these frame designs? Explain your answer.
