Applied Mechanics and Graphic Statics The forces which meet at one point and have their lines of action in different planes are called Intersecting forces Coplanar non-concurrent forces Non-coplanar non-current forces Non-coplanar concurrent forces Intersecting forces Coplanar non-concurrent forces Non-coplanar non-current forces Non-coplanar concurrent forces 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 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 w sin (φ - θ)/cos φ ANSWER DOWNLOAD EXAMIANS APP
