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: 60 g 100 g 40 g 80 g 60 g 100 g 40 g 80 g ANSWER DOWNLOAD EXAMIANS APP
