Some people modify cars to be much closer to the ground than when manufactured. Should they install stiffer springs? Explain your answer.
A fisher caught a fish 5.0 kg striped bass and the fishing line is 0.55mm in diameter. When the fish is pulled in and hangs vertically from the line out of the water, what is the fractional increase in length (ΔL/L0) of the fishing line if the fish is at rest? The fishing line has a Young's modulus of 5.1×109N/m2. Assume that the force did not exceed the elastic region of the fishing line material.

A shaft having length equal to 10 m and diameter equal to (50 + 21) mm is simply supported at both ends. The shaft carries four masses (150 + 21) kg, (200 + 22) kg, (250 + 21) kg and (300 + 21) kg. These masses are located at a distance of 1.5 m, 2.5 m, 5.5 m and 7.5 m from the left hand side support, respectively. The modulus of elasticity, E, for the material of the shaft is 200 GN/m2 and mass density for the shaft material is 7500 kg/m3. Determine critical speed of the shaft in revolutions per minute for the following two cases: i. Effect of the mass of the shaft is neglected. ii. Effect of the mass of the shaft is considered. What is the usefulness of the answers determined in this problem?

In the Challenger Deep of the Marianas Trench, the depth of seawater is 10.9 km and the pressure is 1.16×10^8 Pa, (about 1150 atmospheres).

Assume that the bulk modulus for seawater is the same as for freshwater 2.2×10^9 Pa. Report in cubic meters.
