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) 44079 43898 43959 43832 44079 43898 43959 43832 ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A train weighing 196 tonnes experiences a frictional resistance of 5(11/22) per tonne. The speed of the train at the top of a down gradient 1 in 78.4 is 36 km/hour. The speed of the train after running 1 km down the slope, is 10 √5 m/sec 5 √3 m/sec 5 √10 m/sec 3 √5 m/sec 10 √5 m/sec 5 √3 m/sec 5 √10 m/sec 3 √5 m/sec ANSWER DOWNLOAD EXAMIANS APP
