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 = C - mW P = m/W + C P = mW - C P = mW + C P = C - mW P = m/W + C P = mW - C ANSWER DOWNLOAD EXAMIANS APP

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 up towards direction of pull None of these Slant down towards direction of pull Remain horizontal Slant up towards direction of pull None of these Slant down towards direction of pull Remain horizontal ANSWER DOWNLOAD EXAMIANS APP
