Applied Mechanics and Graphic Statics A string of length 90 cm is fastened to two points ‘A’ and ‘B’ at the same level 60 cm apart. A ring weighing 120 g is slided on the string. A horizontal force ‘P’ is applied to the ring such that it is in equilibrium vertically below ‘B’. The value of ‘P’ is: 40 g 100 g 60 g 80 g 40 g 100 g 60 g 80 g ANSWER DOWNLOAD EXAMIANS APP
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 1.5 m/sec 2.5 m/sec 3.5 m/sec 0.5 m/sec 1.5 m/sec 2.5 m/sec 3.5 m/sec ANSWER DOWNLOAD EXAMIANS APP
