Hence, drawing f g parallel to ab through o, the lines/V7, ge, etc.,denote the elongations and compressionsof the respective fibers, and we see fromthe figure that od:odr \\df: df or the change of length in the fibers isproportional to their… … Hence, by combining these two proportions, H : H ; I o d : o dror, the horizontal forces are directly pro- portional to their distances from theneutral axis. Therefore, if we denotethe distance of any fiber from the axisby 2 the strain upon it by H, the distance of the remotest fiber by e and…
