Question

Breaking stress of an iron rope is 6x10° Pa. w It is used to measure depth of sea. The maximum depth that can be measured with the iron rope is (Young's modulus of iron is 5x10° Pa, density of iron is 4000 kg/m", g=10m/s2)

Answer 1

Answer:

The answer is 150 m.

Explanation:

As we know that

Breaking stress = Lρg

6x10^6 = L x 4000 x 10

L = 6x10^6/4000 X 10

L = 6x10^6/40000

L = 150 m

Thus the maximum depth that can be measured with the iron rope is 150 m.
