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 car goes round a curve of radius 100 m at 25 m/sec. The angle to the horizontal at which the road must be banked to prevent sideways friction on the car wheels is tan"1 x, where x is (Assume g = 10 m/sec²) 43898 44079 43832 43959 43898 44079 43832 43959 ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics Two balls of masses 3 kg and 6 kg are moving with velocities of 4 m/sec and 1 m/sec respectively, towards each other along the line of their centers. After impact the 3 kg ball comes to rest. This can happen only if the coefficient of restitution between the balls is 43833 43864 43895 43835 43833 43864 43895 43835 ANSWER DOWNLOAD EXAMIANS APP
