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 4√(gra/h) ∛(gra/h) √(gra/h) gra/h 4√(gra/h) ∛(gra/h) √(gra/h) ANSWER DOWNLOAD EXAMIANS APP
