The force generated by a spring is given by F = kx, where k is the spring constant and x is the deflection of the spring. The spring of Fig. P1–99 has a spring constant of 8 kN/cm. The pressures are P1 = 5000 kPa, P2 = 10,000 kPa, and P3 = 1000 kPa. If the piston diameters are D1 = 8 cm and D2 = 3 cm, how far will the spring be deflected?
Consider a tilted surface with an angle of 30 degrees. Oil (µ = 0.025 Pa.s) covers the inclined surface, and when a cubic object with a height of 0.1 m is placed on the tilted surface, a liquid film of 0.5 mm occurs. Suppose that the object slides down the surface with a constant velocity of 0.2 m/s. Determine the mass (in gram) and density of the object (in kg/m3).

The density of mercury changes approximately linearly with temperature as ρ=851.5-0.086T in lbm/ft^3 (T in degrees F), so the same pressure difference will result in a manometer reading that is influenced by temperature.
