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 Remain horizontal Slant up towards direction of pull Slant down towards direction of pull None of these Remain horizontal Slant up towards direction of pull Slant down towards direction of pull ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics The maximum frictional force, which comes into play, when a body just begins to slide over the surface of the other body, is known as Dynamic friction Coefficient of friction Static friction Limiting friction Dynamic friction Coefficient of friction Static friction Limiting friction ANSWER DOWNLOAD EXAMIANS APP
Engineering Mechanics The law of the machine is (where P = Effort applied to lift the load, m = A constant which is equal to the slope of the line, W = Load lifted, and C = Another constant which represents the machine friction.) P = mW + C P = mW - C P = m/W + C P = C - mW P = mW + C P = mW - C P = m/W + C P = C - mW ANSWER DOWNLOAD EXAMIANS APP
