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) 4√(gra/h) ∛(gra/h) gra/h √(gra/h) 4√(gra/h) ∛(gra/h) ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A body A of mass 6.6 kg which is lying on a horizontal platform 4.5 m from its edge is connected to the end of a light string whose other end is supporting a body of mass 3.2 kg as shown in below figure. If the friction between the platform and the body A is 1/3, the acceleration is 1.25 m/sec² 0.75 m/sec² 1.00 m/sec² 0.5 m/sec² 1.25 m/sec² 0.75 m/sec² 1.00 m/sec² 0.5 m/sec² ANSWER DOWNLOAD EXAMIANS APP
