Applied Mechanics and Graphic Statics A block of weight 50 kg is placed on a horizontal plane. When a horizontal force of 18 kg is applied, the block is just on the point of motion. The angle of friction is 20° 48' 18° 48' 17° 48' 19° 48' 20° 48' 18° 48' 17° 48' 19° 48' 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 (φ - θ)/cos φ w sin (θ - φ)/cos φ w sinθ cos(θ - φ)/sin φ w cos (θ + φ)/cos φ w sin (φ - θ)/cos φ w sin (θ - φ)/cos φ w sinθ cos(θ - φ)/sin φ w cos (θ + φ)/cos φ ANSWER DOWNLOAD EXAMIANS APP
