Find the increase in pressure required to decrease the volume of a water sample by 0.01%. Bulk modulus of water = 2.1 × 10⁹ N m^-2.

A steel wire of original length 1 m and cross-sectional area 4.00 mm² is clomped at the two ends so that it lies horizontally and without tension. If n load of 2.16 kg is upending from (he middle point of the wire, what would be its vertical depression? Y of the steel = 2.0 × 10¹¹ N m^-2. Take
g 10 m s^-2.

A topper wire of cross-sectional area 0.01 cm is under tension of 20 N. Find the decrease in the cross-sectional area Young modulus of copper = 1.1 × 10¹¹ N m^-2 and Poisson ratio = 0.32.

Estimate the change in the density of water in ocean at a depth of 400 m below the surface. The density of water at the surface 1030 kg m^-3 and the bulk modulus of water = 2 × 10⁹ N m^-2.

A steel plate of face area 4 cm² and thickness 0.5 cm is fixed rigidly at the lower surface. A tangential force of 10 N is applied on the upper surface. Find the lateral displacement of the upper surface with respect to the lower surface. Rigidity modulus of steel = 8.4 × 10¹⁰ N m^-2.
