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 = 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 α = β/2 - π/2 ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A ladder of weight 'w' rests against a smooth vertical wall, and rests on rough horizontal ground, the coefficient of friction between the ladder and the ground being 1/4. The maximum angle of inclination of the ladder to the vertical, if a man of weight 'w' is to walk to the top of it safely, is tan'1 x, where x is 4 43833 3 43834 4 43833 3 43834 ANSWER DOWNLOAD EXAMIANS APP
