The truth is that it is not, hence the survival tips mentioned at the beginning of this section. This is counter-intuitive as most assume that the door would be relatively easy to open. Note as well that the dimensions in many of the images will not be perfectly to scale in. In each case consider the top of the blue box to be the surface of the water in which the plate is submerged. Find the hydrostatic force on the following plates submerged in water as shown in each image. Wall In Exercises 712, find the fluid force on the vertical side of the tank, where the dimensions. Section 8.4 : Hydrostatic Pressure and Force. Most adults would find it very difficult to apply over 500 lb of force to a car door while seated inside, making the door effectively impossible to open. the fluid force on a submerged horizontal surface of. Using the weight-density of water of 62.4 lb/ft 3, we have the total force as We adopt the convention that the top of the door is at the surface of the water, both of which are at y = 0.
Its length is 10 / 3 ft and its height is 2.25 ft. SolutionThe car door, as a rectangle, is drawn in Figure 6.5.7.
