Applied Mechanics and Graphic Statics The masses of two balls are in the ratio of 2 : 1 and their respective velocities are in the ratio of 1 : 2 but in opposite direction before impact. If the coefficient of restitution is ½, the velocities of separation of the balls will be equal to Half the original velocity in the opposite direction Half the original velocity in the same direction Original velocity in the same direction Original velocity in the opposite direction Half the original velocity in the opposite direction Half the original velocity in the same direction Original velocity in the same direction Original velocity in the opposite direction 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 wl²/16d wl²/8d wl/4d wl²/4d wl²/16d wl²/8d wl/4d wl²/4d ANSWER DOWNLOAD EXAMIANS APP
