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) 43832 43898 44079 43959 43832 43898 44079 43959 ANSWER DOWNLOAD EXAMIANS APP
