27. Calculate the work required to lift a 10-m chain over the side of
a building (Figure 13) Assume that the chain has a density of 8 kg/m.
Hint: Break up the chain into N segments, estimate the work performed
on a segment, and compute the limit as N → ∞ as an integral.
Segment of
length Ay
FIGURE 13 The small segment of the chain of length Ay located y
meters from the top is lifted through a vertical distance y.
