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/2 + β/2 α = π/4 - β/2 α = π/4 - β/2 α = β/2 - π/2 α = π/2 + β/2 α = π/4 - β/2 α = π/4 - β/2 ANSWER DOWNLOAD EXAMIANS APP
Applied Mechanics and Graphic Statics A vehicle weighing w kg is to run on a circular curve of radius r. If the height of its centre of gravity above the road level is h and the distance between the centres of wheels is 2a, the maximum velocity, in order to avoid over turning, will be ∛(gra/h) gra/h √(gra/h) 4√(gra/h) ∛(gra/h) gra/h √(gra/h) 4√(gra/h) ANSWER DOWNLOAD EXAMIANS APP
