Applied Mechanics and Graphic Statics A ball moving with a velocity of 5 m/sec impinges a fixed plane at an angle of 45° and its direction after impact is equally inclined to the line of impact. If the coefficient of restitution is 0.5, the velocity of the ball after impact will be 0.5 m/sec 3.5 m/sec 2.5 m/sec 1.5 m/sec 0.5 m/sec 3.5 m/sec 2.5 m/sec 1.5 m/sec ANSWER DOWNLOAD EXAMIANS APP
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 wl²/8d wl/4d wl²/16d wl²/4d wl²/8d wl/4d wl²/16d wl²/4d ANSWER DOWNLOAD EXAMIANS APP
