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 60 g 80 g 100 g 40 g 60 g 80 g 100 g ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A vehicle weighing w kg is to run on a circular curve of radius r. If the height of its centre of gravity above the road level is h and the distance between the centres of wheels is 2a, the maximum velocity, in order to avoid over turning, will be gra/h ∛(gra/h) √(gra/h) 4√(gra/h) gra/h ∛(gra/h) √(gra/h) 4√(gra/h) ANSWER DOWNLOAD EXAMIANS APP
