Question

For a given material, Young's modulus is 110 GN/m2 and shear modulus is 42 GNIm?. Find the Bulk modulus and lateral contraction of a round bar of 37.5 mm diameter and 2.4 m length when stretched 2.5 mm ?​

Answer 1

Answer:

The answer is 110GN/m^2

Explanation:

Data:

1) Young's modulus (Y) = 110GN/m^2

2) Diameter of the cylinder = 3.75*10^(-2)m

3) L = 2.4m

4) change in length= 2.5 mm

First we will find the force F by using the formula of Young's modulus which is

$y = \frac{force \times length}{area \times change \: in \: length}$

From here

F=3.55*10^8 N

Now by the formula of bulk modulus that is

$k = \frac{force \times volume}{area \times change \: in \: volume}$

From this

K=110 GN/m^2
