Your first foray into ice fishing takes a bad turn when a sudden overnight thaw sends your shack to the bottom of the lake with you sleeping inside, as shown in Figure P2.56. Luckily your shack is completely watertight and maintains atmospheric pressure inside. It settles on the bottom at an angle 0. On one wall of the shack (the one pointing down in the figure), there is a square window measuring H/3 on a side that is hinged on the top and swings outward. The top of the window is 3H below the surface. (a) What is the minimum force required to open the window, in terms of p, g, H and 0? (b) Where would you need to apply this force, in terms of H and ? (hinge) EIH H/3 (left wall) 311 hinge H/3 Figure P2.56 Your first foray into ice fishing takes a bad turn when a sudden overnight thaw sends your shack to the bottom of the lake with you sleeping inside, as shown in Figure P2.56.
