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 4√(gra/h) √(gra/h) gra/h ∛(gra/h) 4√(gra/h) √(gra/h) gra/h ∛(gra/h) ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A stone was thrown vertically upwards from the ground with a velocity of 50 m/sec. After 5 seconds another stone was thrown vertically upwards from the same place. If both the stones strike the ground at the same time, then the velocity with which the second stone was thrown should be (Assume g = 10 m/sec²) 25 m/sec 15 m/sec 50 m/sec 40 m/sec 25 m/sec 15 m/sec 50 m/sec 40 m/sec ANSWER DOWNLOAD EXAMIANS APP
