## The Marina 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 ×108 Pa . A steel ball of initial volume 3 0.32 m is dropped into the ocean and falls to the bottom of the trench. What is the change in the volume of the ball when it reaches to the bottom?

## A rod of length 1.05 m having negligible mass is supported at its ends by two wires of steel (wire A) and aluminium (wire B) of equal lengths as shown in Fig. 9.15. The cross-sectional areas of wires A and B are 1.0 mm2 and 2.0 mm2, respectively. At what point along the rod should a mass m be suspended in order to produce (a) equal stresses and (b) equal strains in both steel and aluminium wires.
