Applied Mechanics and Graphic Statics For the given values of initial velocity of projection and angle of inclination of the plane, the maximum range for a projectile projected upwards will be obtained, if the angle of projection is α = β/2 - π/2 α = π/4 - β/2 α = π/2 + β/2 α = π/4 - β/2 α = β/2 - π/2 α = π/4 - β/2 α = π/2 + β/2 α = π/4 - β/2 ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics Newton’s Law of Motion is: The rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction, in which the force acts All listed here To every action, there is always an equal and opposite reaction Everybody continues in its state of rest or of uniform motion in a straight line, unless it is acted upon by some external force The rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction, in which the force acts All listed here To every action, there is always an equal and opposite reaction Everybody continues in its state of rest or of uniform motion in a straight line, unless it is acted upon by some external force 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 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 w sin (θ - φ)/cos φ w sinθ cos(θ - φ)/sin φ w sin (φ - θ)/cos φ ANSWER DOWNLOAD EXAMIANS APP
