Determine the pressure required to reduced the given volume of water by 1% (Bulk modulus or water=2x10^8 N/m²)

A weight of 125 Newton is attached to a brass wire of 7.5 meters long. Young’s modulus for brass is 8.96 X 10^11 Pa. The radius of the wire is 0.7 mm. What is the change in its length in meter?

A plank 2.00 cm thick and 16.3 cm wide is firmly attached to the railing of a ship by clamps so that the rest of the board extends 2.00 m horizontally over the sea below. A man of mass 67.7 kg is forced to stand on the very end. If the end of the board drops by 5.40 cm because of the man's weight, find the shear modulus of the wood. 75376.05

Suppose a piano tuner stretches a steel piano wire 5.5 mm. The wire was originally 0.825 mm in diameter, 1.27 m long, and has a Young's modulus of 2.10 × 1011 N/m2. l0 = 1.27 ml = 5.5 mmd = 0.825 mm Calculate the force a piano tuner applies to stretch the steel piano wire in Newtons. F =

Some claim that mountain climbers suffer from headaches due not only to a lack of oxygen in the brain, but also to the expansion of the brain in the cranium. Find the fractional change of the brain's volume due to a reduction in pressure from (1.48x10^2) kPa at sea level to 27.0 kPa high in the Himalayas. The bulk modulus is 2.10 GPa. Give your answer with three significant figures. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: x10 Answer

6. A) A 100-kg load is hung on a wire of length 6.00-m, diameter 2.00-mm, and Young's modulus 8.00 x 1010 N/m². What is its increase in length?
