Applied Mechanics and Graphic Statics In a lifting machine a weight of 5 kN is lifted through 200 mm by an effort of 0.1 kN moving through 15 m. The mechanical advantage and velocity ratio of the machine are respectively 75 and 75 50 and 50 50 and 75 75 and 50 75 and 75 50 and 50 50 and 75 75 and 50 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 sinθ cos(θ - φ)/sin φ w sin (θ - φ)/cos φ w cos (θ + φ)/cos φ w sin (φ - θ)/cos φ w sinθ cos(θ - φ)/sin φ w sin (θ - φ)/cos φ w cos (θ + φ)/cos φ w sin (φ - θ)/cos φ ANSWER DOWNLOAD EXAMIANS APP
