Applied Mechanics and Graphic Statics The ends of a string weighing w/metre are attached to two points at the same horizontal level. If the central dip is very small, the horizontal tension of the string throughout is wl²/16d wl/4d wl²/4d wl²/8d wl²/16d wl/4d wl²/4d wl²/8d ANSWER DOWNLOAD EXAMIANS APP
