This Tactics Box outlines a set of rules forthinking about such hydrostatic problems.1. Draw a picture. Show open surfaces, pistons, boundaries, and other features that affect the pressure.Include height and area measurements and fluid densities. Identify the points at which you need to find thepressure. These objects make up the system; the environment is everything else.2. Determine the pressure at the various surfaces.Figure1 of 1• For a surface open to the air, po = Patm, usually 1 atm.• For a surface covered by a gas, po = Pgas-• For a closed surface, p = F/A, where F is the force the surface, such as a piston, exertson the fluid and A is the area of the surface.3. Use horizontal lines. Pressure in a connected fluid is the same at any point along a horizontal line.4. Allow for gauge pressure. Pressure gauges read pe =p-1 atm.5. Use the hydrostatic pressure equation: p = po + pgh, where p is the density of the fluid, g is the free-fallacceleration, and h is the height of the fluid.PeasAUse these rules to work out the following problem: A U-shaped tube is connected to a box at one end and open to the airat the other end. The box is full of gas at pressure Pgas, and the tube is filled with mercury of density 1.36x104 kg/m .When the liquid in the tube reaches static equilibrium, the mercury column is h1 = 15.0 cm high in the left arm and h2 =6.00 cm high in the right arm, as shown in the figure.(Figure 1) What is the gas pressure pgas inside the box?h2mercury I Review| ConstantsLearning Goal:To practice Tactics Box 14.1 Hydrostatics.Part CIn problems about liquids in hydrostatic equilibrium, youoften need to find the pressure at some point in theliquid.

(2) The box with M = 40kg shown below is being pulled by two pulleys exerting forces F₁ = 400 N (0₁ = 60°) and F₂ = 200 N (0₂= 15°) up an incline with an angle 0₁ = 30°. If the uk = 0.15. What is the acceleration of the box? Would the F₁ or F₂ be enough alone to pull the box up if the other pulley would stop working?
