what is the magnitude of the force exrted on the side and circular base of the tank

So, first of all, let’s start by finding the area of the base of the tank. Which is exactly what we need to do in this question. So, based on all of this, we can work out the force exerted or, in other words, the weight of the tank. Because we know the side lengths of the base of the tank.

And as well as this, we have enough information to work out the area of the base of the tank. Now, in the question, we’ve actually already been told the pressure exerted by the weight of the tank. Because, once again, that area is the area over which the force is distributed. We know that the pressure exerted by the weight of the tank is equal to the weight of the tank divided by the area of the base of the tank. So, in our situation where we’ve got the tank exerting a force, that’s the weight of the tank, onto the surface that it’s resting on. Now at this point, we can recall that the pressure exerted on a surface, which we’ll call 𝑃, is given by the force exerted on that surface divided by the area of that surface. And that force is distributed over the entire base.

This is because all of the tank’s weight, the weight 𝑊, is the force applied to the surface that the tank is resting on. As well as this, the area over which that weight is distributed is simply the area of the base of the tank.

And this weight of the tank is exactly the force that the tank itself exerts on the surface that it’s resting on. Now, the weight of the tank is acting in a downward direction, and we’ll call it 𝑊. So, lets draw the surface in here because we’ve been told that the weight of the tank applies a pressure of 350 pascals to the surface it’s resting on. As well as this, we’ve been told that the tank is resting on a surface. So, that’s this face over here, which has side lengths of 2.3 metres and 1.2 metres. Okay, so in this question, we’ve been told that we’ve got an empty water tank. The weight of the tank applies a pressure of 350 pascals to the surface it is resting on. An empty water tank has a rectangular base with side lengths of 1.2 metres and 2.3 metres.
