1.A cone penetration test has been conducted and has measured a con resistance of 85 kg/cm^3 at a depth of 10m. the vertical effective stress at this depth is 159KPa and the over consolidation ratio is 2, The soils at this depth are quartz sands. Compute the relative density.

2.When a fluid flows through a sharp bend, low pressures may develop in localized regions of the bend. Estimate the minimum absolute pressure (pmin in psi) that can develop without causing cavitation if the fluid is water at 80 oF.

3.A high altitude balloon has a long steel wire hanging from it. The length of the wire is 7,000 m, the weight density of the steel is 78 kN/m3 and its ultimate stress is 620 MPa. Find the safety factor of the wire against breaking from its own weight.
