![]() ![]() "PC", C for chimpanzee, it's going to be the Pressure due to the chimpanzee on the ice, let's call this A small thing over here is over here, the area is in centimeter square, so we need to be a littleĬareful before we compare. And if you have not tried this before, again, now would be a great It's 1500 Newtons per meter square, which we can also call And so, that's the pressureĭue to the gorilla. Second is the unit of force, unit of weight, and that isĪlso called Newtons, right? Divided by 1, which is 1500, and we have meter squared That's going to be 1500 kilogram meters per second squared, but kilograms meter per Okay, what's that gonna be? Well, let's write it down here. Ten meters per second, squared, divided by the area of content. It's going to be the mass of the gorilla, and it's 150 kilograms, times g, which, we are assuming, to be ![]() All right, so let's first do pressure of, pressure due to the gorilla on the ice. Meter per second squared, instead of 9.8, okay? So, pause the video and How to calculate pressure, can you try and calculate who's putting more pressure on the ice first? Good, give it a shot, and just to make the calculation simple, let's assume g to be 10 More clarity over there, feel free to go back and check that. And again, we have spoken a lot about why weight equals m g and previous videosĬalled, "Mass and Weight. And therefore, in ourĮxample, the pressure will be m g, divided by the area. Weight is a force due to gravity, right? And how do we calculate force? Well, if you use Newton's second law, force equals mass times acceleration, and since you're dealing with gravity, that acceleration will be g. And how do we calculate their weight? Weight is not that same thing as mass. Will calculate that pressure as their weight divided by the area. Pressing on that thin ice, which could break that ice, isn't it? So, this force, in our example, is going to be their weights. ![]() To their weight, isn't it? That's the one that is Anyways, in our example, whichįorce are we talking about? Hey, it's the force due This formula comes from, get ready to go back and watch that video. This, in a previous video called "Thrust and Pressure." And so if you need more clarity on, you know, where That's what it is: how much force is gettingĭivided by the area, right? And, we've talked a lot about ![]() And how do we calculate pressure? We calculate pressure as force divided by area. More pressure, moreĬhances of breaking it. It's the pressure that tells us whether something is It's the pressure which tells us how concentrated the force is. Is not just the force, but what also matters Were to put that same force on that same paper, but now, you went to push it through a pin, I'm pretty sure you canĮasily puncture that, puncture that paper, right? Pierce through that paper, why? It's not because you put moreįorce, but because over here, notice the force wasĭivided over a large area, but here the force wasĬoncentrated into a tiny area. That paper, right? On the other hand, if you Were to push on a paper, with your thumb, there's a goodĬhance you won't break that, you won't pierce through Weight could break that ice." Right? But remember, whether youĬan break something or not, not just depends upon your force, but also depends upon howĬoncentrated that force is. So much more than the chimp, so it's definitely his Likely to break that ice? Now, at first, we might think, "Hey, gorilla definitely weighs Let's say that area isĪbout a meter squared, and remember, a meter is 100 centimeters, so this area is much bigger than this one. Is sleeping on his side, the gorilla is large, that area of contact Let's say that area is aboutġ00 centimeters squared. The chimpanzee is standing, the area of contact with Weighs about 30 kilograms, and let's say the gorilla We wanna try and answer in this video, is figure out whose weight is more likely to break this ice? Is it the chimpanzee's or the gorilla's? Now, before we come to any conclusion, let's first look at some data. Now, because the ice is pretty thin, their weights can break the ice, right? It's possible because of their weights. Standing on a very thin ice in the middle of some ocean. Say a gorilla is sleeping, and a chimpanzee is ![]()
