A container of fluid has two doors; door 1 is a horizontal door at the bottom, and door 2 is inclined at an angle to the horizontal, as shown in figure Q2. Both doors have a square cross-sectional area; door 1 has an area L x L, and door 2 has an area (2L) x (2L). The depth of the fluid is ho. Find the vertical force on door 1. Find the moment due to static pressure on door 1 about its hinge. The hinge is at the left of the door, as shown in the figure. Find the moment due to static pressure on door 2 about its hinge. The hinge is at the left of the door, at a depth ho, as shown in the figure. If the moment on door 2 is 4 times larger than the moment on door 1, find ho in terms of L and 8

Classification of types of corrosion

Corrosion is described as the process in which a certain element is degraded or deteriorated due to the presence of multiple chemicals in the surrounding. Generally, corrosion happens if all the subatomic particles on a metallic object are oxidized, for example, rust on iron structures. In air or water, metals lose electrons to other particles (like oxygen), leading to the formation of an oxide with the metal.
