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 cos (θ + φ)/cos φ w sinθ cos(θ - φ)/sin φ w sin (φ - θ)/cos φ w sin (θ - φ)/cos φ w cos (θ + φ)/cos φ w sinθ cos(θ - φ)/sin φ w sin (φ - θ)/cos φ w sin (θ - φ)/cos φ ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics The masses of two balls are in the ratio of 2 : 1 and their respective velocities are in the ratio of 1 : 2 but in opposite direction before impact.
