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 Remain horizontal 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 ANSWER DOWNLOAD EXAMIANS APP
