Applied Mechanics and Graphic Statics A particle moves along a straight line such that distance ‘x’ traversed in ‘t’ seconds is given by x = t²(t + 1), the acceleration of the particle, will be 6t - 2 3t² + 2t 6t + 2 3t³ - 2t 6t - 2 3t² + 2t 6t + 2 3t³ - 2t 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 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 w sinθ cos(θ - φ)/sin φ ANSWER DOWNLOAD EXAMIANS APP
