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