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 wl²/4d wl²/16d wl/4d wl²/8d wl²/4d wl²/16d wl/4d wl²/8d ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A vehicle weighing w kg is to run on a circular curve of radius r. If the height of its centre of gravity above the road level is h and the distance between the centres of wheels is 2a, the maximum velocity, in order to avoid over turning, will be ∛(gra/h) 4√(gra/h) gra/h √(gra/h) ∛(gra/h) 4√(gra/h) gra/h √(gra/h) ANSWER DOWNLOAD EXAMIANS APP
