What topic in physics is this question coming from?

[Achadu]

It was reported that a mild earthquake occurred in brass with a result that the plate which is 0.8m square of 0.5m thick usually attached to the base of the antenna pole had its edges displaced by 0.016cm. If the plate is made of brass with a shear modulus of 0.36 x 10^11 N/m². Find the force exerted by the earthquake on the plate.

Well the question is a simple application of properties of materials or strength of (solid) materials.

What do you know about the definition of the shear modulus? (The figure quoted is about right for brass)

[Achadu]

I know nothing about shear modulus
