Unformatted text preview: makes the V curve jump up by F . 6.) A concentrated clockwise couple C makes the M curve jump up by C . (note clockwise ) Using these six facts for plotting V and M diagrams (2 slope theorems, 2 area/change theorems and 2 jump theorems) makes it quick and easy. Generally, the slopes guide the shapes and the changes/jumps determine values of key points. No equations need to be found. If equations for V(x) and M(x) are needed, the fbd of length x (Section 5.2) method is appropriate. However, you should cross out page 314! Page 315 is a much better example of the fbd of length x method for obtaining equations....
