Question

Two rods are made from materials that have different Young’s moduli. The rods are constructed to have the same length and same cross-sectional area. The same forces pull similarly on each rod. The rod with the larger Young’s modulus will stretch more than the rod with the smaller Young’s modulus.

A. True

B. False

Answer:False

Explanation:Let the Young’s modulus of two different material is Y and Y’

Let F is the force applied, L is the initial length and A is the area of crossection.

By the formula of Young’s modulusIncrease in length is inversely proportional to the Young’s modulus, so more is the value of Young’s modulus lesser be the extension in the length of rod.Thus, the given statement is false.
