Engineering Mechanics A semicircular disc rests on a horizontal surface with its top flat surface horizontal and circular portion touching down. The coefficient of friction between semi circular disc and horizontal surface is µ. This disc is to be pulled by a horizontal force applied at one edge and it always remains horizontal. When the disc is about to start moving, its top horizontal force will Slant down towards direction of pull Slant up towards direction of pull None of these Remain horizontal Slant down towards direction of pull Slant up towards direction of pull None of these Remain horizontal 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 = 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 t = g cos β/2u sin (α - β) t = g cos β/2u sin (α + β) t = 2u sin (α - β)/g cos β ANSWER DOWNLOAD EXAMIANS APP
