The platform scale consists of a combination of third and first class levers so that the load on one lever becomes the effort that moves the next lever. Through this arrangement, a small weight can balance a massive object. If x = 450 mm, and the mass of the counterweight S is 2 kg, determine the mass of the load L required to maintain the balance.
