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 43832 43959 43898 44079 43832 43959 43898 ANSWER DOWNLOAD EXAMIANS APP

Applied Mechanics and Graphic Statics A body of weight ‘w’ placed on an inclined plane is acted upon by a force ‘P’ parallel to the plane which causes the body just to move up the plane. If the angle of inclination of the plane is ‘θ’ and angle of friction is ‘φ’, the minimum value of ‘P’, is w sin (θ - φ)/cos φ w sin (φ - θ)/cos φ w cos (θ + φ)/cos φ w sinθ cos(θ - φ)/sin φ w sin (θ - φ)/cos φ w sin (φ - θ)/cos φ w cos (θ + φ)/cos φ w sinθ cos(θ - φ)/sin φ ANSWER DOWNLOAD EXAMIANS APP
