Figure (Figure 1) shows how a scale with a capacity of only 250 NN can be used to weigh an object that is heavier than that. The board is 3.0 mm long, has a mass of 3.4 kgkg, and is of uniform density. What is the weight of an object that is 1.2 mm from the pivot end, if the scale reads 170 NN? Assume that the beam remains nearly horizontal. Express your answer with the appropriate units. W0=?
