Engineering Mechanics Non-coplanar concurrent forces are those forces which Meet at one point and their lines of action also lie on the same plane Meet at one point, but their lines of action do not lie on the same plane Do not meet at one point and their lines of action do not lie on the same plane Do not meet at one point, but their lines of action lie on the same plane Meet at one point and their lines of action also lie on the same plane Meet at one point, but their lines of action do not lie on the same plane Do not meet at one point and their lines of action do not lie on the same plane Do not meet at one point, but their lines of action lie on the same plane ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics The time of flight (t) of a projectile on an upward inclined plane is(where u = Velocity of projection, α = Angle of projection, and β = Inclination of the plane with the horizontal.) t = g cos β/2u sin (α - β) t = g cos β/2u sin (α + β) t = 2u sin (α - β)/g cos β t = 2u sin (α + β)/g cos β t = g cos β/2u sin (α - β) t = g cos β/2u sin (α + β) t = 2u sin (α - β)/g cos β t = 2u sin (α + β)/g cos β ANSWER DOWNLOAD EXAMIANS APP
