Mechanical Properties of Solids

Question : 14

Total: 21

Compute the fractional change in volume of a glass slab, whensubjected to a hydraulic pressure of 10 atm.

Solution:

Here, P=10‌atm=10×1.013×105Pa
Bulk modulus of glass B=37×109N m−2
Volumetric strain =

ΔV

10×1.013×105

37×109

=2.74×10−5
∴ Fractional change in volume =

ΔV

=2.74×10−5
