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 None of these Slant up towards direction of pull Remain horizontal Slant down towards direction of pull None of these Slant up towards direction of pull Remain horizontal Slant down towards direction of pull ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics Angle of friction is the Ratio of limiting friction and normal reaction The ratio of minimum friction force to friction force acting when the body is in motion Angle between normal reaction and the resultant of normal reaction and the limiting friction The ratio of minimum friction force to the friction force acting when the body is just about to move Ratio of limiting friction and normal reaction The ratio of minimum friction force to friction force acting when the body is in motion Angle between normal reaction and the resultant of normal reaction and the limiting friction The ratio of minimum friction force to the friction force acting when the body is just about to move ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics The three forces of 100 N, 200 N and 300 N have their lines of action parallel to each other but act in the opposite directions.
