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 43959 43898 44079 43832 43959 43898 44079 ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics The following is not a law of static friction: The force of friction is dependent upon the area of contact The force of friction always acts in a direction opposite to that in which the body tends to move The magnitude of the limiting friction bears a constant ratio to the normal reaction between two surfaces The force of friction depends upon the roughness of the surface The force of friction is dependent upon the area of contact The force of friction always acts in a direction opposite to that in which the body tends to move The magnitude of the limiting friction bears a constant ratio to the normal reaction between two surfaces The force of friction depends upon the roughness of the surface ANSWER DOWNLOAD EXAMIANS APP
