of ed. Similarly the reaction at D is repre-sented by Oq, where q is the middle point of de. 2. Any number of equal bars are connected by smoothpins and two extremities fixed, if the system hangs freelythe bars make angles with the horizon whose tangents arein Arithmetical Progression. Denote the… … Fio. 154. W, through / and e draw fO and eO parallel to f and e, join0 to the points a, b, c, &c. Then as before, the sides of the triangle/eO representthe forces on the pin F, those of the triangle edO the forceson the pin E, and so on. Hence the lines Oe, Od, ... areparallel to the bars e, S…
