Young's moduli of the material of wires A and B are in the ratio of 1 : 4, while its area of cross sections are in the ratio of 1 : 3. If the same amount of load is applied to both the wires, the amount of elongation produced in the wires A and B will be in the ratio of [Assume length of wires A and B are same]
Text Solution
Verified by ExpertsThe correct answer is:
A
The formula to calculate the elongation of a metallic wire because of the application of a load
can be written as
…(i)
The ratio of the elongations for both the wires is, then, calculated as follows-
