SOLUTION: The stretch in a wire under a given tension varies directly as the length of the wire and inversely as the square of its diameter. If the length and the diameter of a wire are both

Question 431841: The stretch in a wire under a given tension varies directly as the length of the wire and inversely as the square of its diameter. If the length and the diameter of a wire are both doubled, what is the effect on the stretch of the wire?
Please and thank you!! :)

Tension =t
length =l
diameter=d
...
t

.....
length doubled = 2l
diameter doubled =2d
t1

t1=2kl/4d^2
t1/t =
t1/t=
t1/t = 2/4 = 1/2
the tension will reduce by 1/2
