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 wl/4d wl²/4d wl²/8d wl²/16d wl/4d wl²/4d wl²/8d wl²/16d ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics When a body of mass M1 is hanging freely and another of mass M2 lying on a smooth inclined plane(α) are connected by a light index tensile string passing over a smooth pulley, the acceleration of the body of mass M1, will be given by g(M1 + M2 sin α)/(M1 + M2) m/sec g(M2 × M1 sin α)/(M2 - M1) m/sec² g(M2 + M1 sin α)/(M1 + M2) m/sec² g(M1 - M2 sin α)/(M1 + M2) m/sec² g(M1 + M2 sin α)/(M1 + M2) m/sec g(M2 × M1 sin α)/(M2 - M1) m/sec² g(M2 + M1 sin α)/(M1 + M2) m/sec² g(M1 - M2 sin α)/(M1 + M2) m/sec² ANSWER DOWNLOAD EXAMIANS APP
