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 sin (φ - θ)/cos φ w cos (θ + φ)/cos φ w sin (θ - φ)/cos φ w sinθ cos(θ - φ)/sin φ w sin (φ - θ)/cos φ w cos (θ + φ)/cos φ ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics One end of an elastic string of natural length / and modulus X is kept fixed while to the other end is attached a particle of mass m which is hanging freely under gravity. The particle is pulled down vertically through a distance x, held at rest and then released.
