Applied Mechanics and Graphic Statics On a mass ‘m’ describing a circular path of radius ‘r’, the centrifugal force Acts away from the centre of rotation Acts towards the centre of rotation Is mw2r/g kgf Acts tangentially to the circular path Acts away from the centre of rotation Acts towards the centre of rotation Is mw2r/g kgf Acts tangentially to the circular path 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 sin (φ - θ)/cos φ w sinθ cos(θ - φ)/sin φ w cos (θ + φ)/cos φ w sin (θ - φ)/cos φ w sin (φ - θ)/cos φ w sinθ cos(θ - φ)/sin φ w cos (θ + φ)/cos φ ANSWER DOWNLOAD EXAMIANS APP

Applied Mechanics and Graphic Statics A string of length 90 cm is fastened to two points ‘A’ and ‘B’ at the same level 60 cm apart. A ring weighing 120 g is slided on the string. A horizontal force ‘P’ is applied to the ring such that it is in equilibrium vertically below ‘B’. The value of ‘P’ is: 60 g 40 g 80 g 100 g 60 g 40 g 80 g 100 g ANSWER DOWNLOAD EXAMIANS APP
