[@rayalhar]

I think a lot of people are taking this the wrong way. It's not a litmus test if you can be an engineer or not. It's an example of a problem and how you'd solve it in an "engineering" mindset with applied concepts and knowledge. A lot of people are going "erm, this is not a 400 level orbital mechanics course so this is not applicable yada yada yada". The way he's solving the problem is a pretty watered down version of what you're going to be doing throughout the time in engineering school. In fact the simpler the content the better so more people have an understanding of what they're getting into. For the people complaining you are taking this the wrong way completely and didn't understand the point of this video at all.

basically the answer is "i dunno", but if you assume that the human's joints are ridgid and he's not trying to balance, and you assume he's more dense than the gas around him then you can assume he's going to fall because his center of mass is so far over his foot.

[@shubhayubanerjeedpsn-std5526]

I agree with the dude saying that a lot of people fail to understand the point of the video. Yes, the title is a little misleading, but the video is solid. He is not asking if you can solve this level of difficulty of question, he is asking/probing how you think about the problem. For a good engineer, is seldom one who remembers all his equations, learns every phenomena, and can solve them well. A good engineer is one who understands how to approach and solve a problem. For in the real world, when you face a problem, you will have all the resources to provide you the formulas, but it is only your intellect that will allow you to use them. And this is from my humble experience as a student. For building multiple model car and vehicles from complete scratch (not model kits), and encountering and learning from the real world, enabled me to much more capable at handling real-world related problems compared to my mentor who has a degree in engineering and learnt about that stuff from a textbook.

[@ChrisJab4]

It's so true that in the real world you will have access to any equation you need to solve the problem. I am still in college (ME) but I can already see that plugging into equations doesn't get you very far as in the real world you are not given all of the numbers. I'm learning that it's how and when to use the equations that actually matters. I just think logically about the problem, use equations when needed to figure out a certain type of force (for example) and it seems to work so far. Not sure if this will work later in college with hydro/thermo dynamics but that's a problem for later lol

[@alithedazzling]

That is a great way to put it! Physics is much more than just memorizing formulas!

[@abhishekpal7291]

Nicely put

[@JackPullen-Paradox]

(1) A thing is unstable when its center of mass falls outside of the base, so the box has to move at a rate that makes the box remain under the person's center of mass. (2) Inertia will cause the person to be destabilized when the box begins to move. (3) Then there is the question of whether the box will slide down the incline. (4) There is also the question of whether the person will slide off the box. These are the four things that come to mind. I have focused on the phrase, "make the person fall," and you actually mean something like slide down the incline or off the box.

I wish we had explainers like this back when I was in school for my EE. My only comment here, was, I'm with you on the frictional component, but the other thing that came to mind was if the diagonal block / ramp and person are not glued down in some manner, their vertical center of mass could also lead to a "tip over fall". Even if you considered the ramp and person to have consistent vertical density, at some unknown height, each would tip over and fall if their frictional component kept them from sliding. That discussion might be a fun video :)

The first question any engineering or physics student should ask is whether the person and box are point particles or extended bodies (systems of particles). Then they should ask if they are rigid. Then the question is what materials are each of the surfaces comprised of. Then when all of that is done, they should ask why the person is standing on a box on an incline plane to begin with.

[@SpaceNerd-YT]

I love this type of explanation! going back to the basics really helps me understand complex physics concepts. I am attempting a masters in Astrophysics right now and even the most complex formulas and concepts can be explained VERY simply if the concept is understood right. (For example recently I had to write a paper about the process of calculating the gravitational redshift of dense celestial objects specifically black holes using the formula Z+1 = 1/root of 1 - 2GM/rc^2, the formula itself looks complicated but the concept is relatively simple to understand with some general physics background information.)

This reminds me of my physics teacher in college. The problems were harder, but the logic and process does not change.

In class, he would advice not to write down everything he is saying, instead try to understand. he would say "do you say i love you to anyone?no, so dont write stuff you don't understand." his tests were either extremely hard or easy.

[@ItsNotAllRainbows_and_Unicorns]

One thing I always remembered well in my physics classes is: g*sin(theta). I did most of the calc just to goggle my mind. It's been a few years, but I think I understand the principle, normal force F_N, static friction F_s, force tangential to the incline F_t. coefficient of static friction, mu_s Normal force: F_N = m*g*cos(theta), Static Friction: F_s = F_N * mu_s Tangential force: F_t = m*g*sin(theta). The one thing to keep in mind is that normal force exerted on the incline is mass of the block plus mass of individual. Next, you will need to calc the normal force on the block, which is the mass of individual standing on top. The tangential forces of block and individual would be m_block*g*sin(theta), and m*individual*g*sin(theta) respectively. To make things easy, with the block "alone", you will find the critical angle when the friction force equals the tangential force, m_block*g*cos(theta) * mu_s = m_block*g*sin(theta) The critical angle, since m_block and g cancel out, leaves tan(theta) = mu_s, you end up solving for theta: atan(mu_s). When you add the 2nd mass (individual), it's a little more complicated but workable.

Here are my first questions in case they may be useful: How is friction acting on the box? It is what as students are always asked to discuss, so it is the first thing that comes to mind) Then, what is falling and where? The box may fall but float on the water depending on box's mass and volume. Then, couldnt he go back and off the box if he had enough time to do so? At last, it may not be such a problem if the guy can swim. Water may just be a swimming pool and he can swim easily to the other side, so falling is not a problem at all. Though if the box is made of metal or some strong material, it could be problematic. If he is in the middle of the sea and the box is made of cardboard, for example, it is a problem. We could also consider the salinity of the water in how it could affect the durability of the box (maybe it could take days to see new land again). I find always good to ask everything you could about the situation. Causes and conseguences, and what could go wrong (or well, equally important), what has gone wrong (and well) I guess if you tend to kind of orderly ask and answer all of these questions and study, you can be a decent engineer

[@alexmoliere570]

When I saw this problem, I looked at what the arrows represented. Now, I'm trying to figure out the values required to determine whether the person is going to fall. The surface area of the box will influence friction, not the box's weight. I think the weight would be affected by gravity, and add more force to the equation. If the force to pull the box grows, then it will require that same amount of force in terms of friction to keep the box on the ramp. Once the force overtakes friction it's going to fall. Then I'm trying to figure out that the angle of the ramp will determine how much friction you'll need to keep the box on the ramp. Like if the ramp is perfectly level, 0 friction is required(you could have a ball), if the ramp angle is 90 degrees, you'd need high friction(like nails implanted). Then the height of the box is gonna be a factor because the center of mass will also be a part of the equation.

Well done from the perspective of 1st year physics this is the basic approach to take and what should be considered first and foremost by engineers. However, another thing to keep in mind is that all these “forces” have assumptions behind them which ought to be listed. For example in understanding normal force and friction force for this example, one can abstract out a single force that roughly captures the behavior, but these things are highly dependent on particularities of the material that require a different paradigm/set of accumulations to analyze precisely.

_"friction coefficients"_ Is it "mass" or is it "moss"????

[@sniperpickaxemc]

Yes, the stick figure will fall, because his centre of mass is past his feet. Therefore, the leverage from gravity coming from the hinge point where his feet's friction are creating an equal and opposite action to gravity, causes him to either slip from not enough friction, or tilt far enough for his feet to stop touching the block, in which case, he falls. If the friction is high enough (like glue, then he would stay, albeit upside down.

We used to teach mechanics, friction, etc in HIGH SCHOOL. Now, we get college applicants who cannot read aloud from a paper they wrote - or who can't even write a paper to begin with.

Yes when block hits water

[@necro-claud6370]

I also like to make a scaling model in the end. Imagining different sizes of block and people, different materials and their relations, how would system behave in different cases.

[@ChuckSploder]

Before the video: yes, the person will fall, because the friction between the block and the ramp will slow the block's acceleration to less than that of gravity, causing the person, who is fully affected by gravity, to fall off the block sooner than the block can catch them. Second hypothesis (by 2:09 in the video): no, he won't, because the horizontal movement of the block catches the person's fall. Third hypothesis: nevermind. It's nearly impossible (for me) to know without knowledge of the friction. Intuitively, he falls.

Bro literally read my mind and knew what I was thinking

[@DanielLaudien-or4yl]

At that picture’s angle I think the better question is whether the guy can counteract the overturning moment from his center of mass standing straight up 😂

At first i went swiftly on the boat, then he added "weight" to the equation and even if i could understand what does it do (depending on the weight it defines if the subject falls or not). I didn't understand "why" the "weight" defines if things fall or not. I had to make a little of engineering myself to understand why the "weight" was so important, going step by step on the topics of the question that i understood already like the importance of the gravity and the friction in the equation, then i went back on the video and realized that we needed to make the another question "If gravity and friction are the things that defines if something falls or stays on place, what defines if the gravity has enough force to pull the object or otherwise the friction has enough force to keep it in place?" "Weight" is the answer Bigger the weight the more friction needed, not enough friction to keep it up with the weight, it will definitely fall. now i have a new question, do i have what it takes to be an engineer even my mind just couldn't understand the question completely without rolling back the explanation?

[@blick7445]

ok what do I do now

[@الحد]

the friction between the human and the block is changing constantly

P.E ,K.E , force and gravity in the situation hold the keys for the answers. Let's examine what is happening, That was my first response. I like maths and physics a lot. I am a big fan of everything maths . I am a clinical pharmacist, but one of my favorite aspects in pharmacy is pharmacokinetics. Beyond the basics, you get many graphs , calculations, statistics, and calculations. My dad was an engineer, his dad was a mathematician, and all of his siblings work in maths related fields , as well as many of my cousins on his side. My mom loves maths and physics. When I studied maths and physics with my mom , she would never give me answers, laws, or equations. She would ask me what is really happening from the givens . What would you do about it ? How would you think about it differently. Everyone expected I would choose to be an engineer. But I wanted to study health and psychology, but still , I think about them as maths, I even wanted to become a brain surgeon, but I have chosen pharmacy, when I knew it has study of maths, health , psychology and beyond. I enjoyed the video. give us more, please.

[@alithedazzling]

oh very nice! what company do you work for? I know a few people in pharmacokinetics!

[@Goldenboii123]

so basically a free body diagram in physics
