Modulus of rigidity of ideal liquid is

The Mariana trench is located in the Pacific Ocean, and at one place it is nearly eleven km beneath the surface of water. The water pressure at the bottom of the Trench is about $1.1\times {10}^8 \mathrm{Pa}$. A steel ball of initial volume $0.32 {\mathrm{m}}^3$ is dropped into the ocean and it falls to the bottom of the trench. What is the change in the volume of the ball when it reaches to the bottom?

Two strips of metal are riveted together at their ends by four rivets, each of diameter $6.0 \mathrm{mm}$. What is the maximum tension that can be exerted by the riveted strip if the shearing stress on the rivet is not to exceed $6.9\times {10}^7 \mathrm{Pa}$? Assume that each rivet is to carry one quarter of the load.

An India rubber cube of side $7 \mathrm{cm}$ has one side fixed while a tangential force equal to weight of $200 \mathrm{kg}$ is applied to the opposite face. Find the shear strain produced and the distance through which the strained side moves. Modulus of rigidity for rubber is $2\times {10}^6 \mathrm{N} {\mathrm{m}}^{-2}$.
