7.1 Problem 24:
Give an explanation of how the values of
21
and xx
affect the spring lengths. Using the
diagram (Figure 7.1.9) for the problem, all three springs are at their natural lengths when
0
21
xx
.
Hint: Does
2
x
affect the length of the first spring?
So the first spring is stretched (or compressed) by…(state the amount in terms of
21
and xx
)
The second spring is stretched (or compressed) by…
The third spring is stretched (or compressed) by …
