The truck rests on the scale, which consists of a series of compound levers. If a mass M1 is placed on the pan P and it is required that the weight is located at a distance x to balance the "beam" ABC, determine the mass of the truck there are pins at all lettered points. Is it necessary for the truck to be symmetrically placed on the scale? Explain.

Units Used:

Mg = 103 kg g = 9.81m/s2

Given:

M1 = 15 kg FD = 3 m

x = 0.480 m EF = 0.2 m

a = 0.2 m

HI = 0.1 m GH = 2.5 m

KJ = HI KG = GH
