amazing content. I do have a concern, though. When you say clockwise moments are positive, this directly contradicts what my prof told me. He said to think of which way the beam bends due to the moment. If the beam makes a happy face then the moment is positive. So given a standard beam, if the moment is on the left side, a clock-wise moment is positive. If the moment is on the right side, a counter clock wise moment is postive. Can you explain your moment sign convention plz
@QuestionSolutions2 жыл бұрын
Moments aren't positive or negative, they are either "clockwise", or "counter-clockwise" in 2D space, and in 3D space, you would use the right hand rule to determine the direction of the vector. Even in 2D space, the moment vector is still determined using the right hand rule. If it's a counterclockwise moment, then the moment vector would be straight of the screen towards you, and vice versa. This is why people usually pick counterclockwise to be positive. I don't like counterclockwise being positive, it's just a personal preference. It makes no difference to the answer. In fact, I encourage you to try it both ways, you will still get the same answer. This is what is important: -If you pick counterclockwise to be positive, and your answer is positive, then your moment is counterclockwise. -If you pick counterclockwise to be positive and your answer is negative, then your moment is clockwise. -If you pick clockwise to be positive and your answer is positive, then your moment is clockwise. -If you pick clockwise to be positive and your answer is negative, then your moment is counterclockwise. You can pick whatever side you want to be positive, like when you pick up to be positive, or down to be positive. It's just an assumption. As a convention, people generally consider positive moments as counterclockwise since they are directed along the positive z axis (out of the screen/page). It's completely up to you.

I really like your content and you've been helping me out a lot. So thank you very much. But I like to point out one stuff. My problem is with example 3 . The result of the support reaction was a bit off for me cause the structure has a moment at the equilibrium and experience more force on the side of A. But the reaction at A is much lower than B ( 450 to 950). So I calculated the support reactions by taking moment at B zero and got different answers which should not be the case. I don't really know what the problem is but something ain't right. ( or I may be super dumb, sorry if that's the case😅)
@QuestionSolutions2 жыл бұрын
Really glad to hear these videos are helping. As per your question, I am assuming something is wrong with how you formulated the moment equation for B. It's hard for me to say where you went wrong without seeing your steps. Also, it's very common for structures to carry forces with varying differences in force values, so you can't assume it's wrong simply because they are very different.

Hi, I understand everything clearly. My only issue is: how do you know what sign convention to use when assigning internal loading directions during sectioning? If you use a positive shear (V), the equation for internal shear turns into a positive slope. The equation would be: V=40x-133.75 which is incorrect, since at x=0, V= -133.75. Yet, when using the method of sections, a positive shear is the correct sign convention. Im at a loss, any clarification would be appreciated, thank you.

Question! On your example three, there is a moment with a magnitude of 1200 N*m. It’s turning clockwise and you treat it as positive, the very next example, there is a moment with magnitude 20 N*m, which is also turning clockwise but you treat it as a negative. Could you explain what is going on there? Im with the impression that counterclockwise is positive and negative for clockwise. Anyhow, great video!
@QuestionSolutions Жыл бұрын
You can pick whatever direction you want to be positive. Depending on the number of negative signs you deal with, you should pick a clockwise or counter-clockwise direction that gives you the least amount of negative signs. That makes your life easier, but if it doesn't, you can always just keep clockwise or counter-clockwise to be positive, it's really up to you. It makes no difference to the answer, because moments aren't positive or negative, they just have directions. So I change the positive side based on what makes the math more simple. It's the same as when you deal with forces. Imagine you have 10 forces down and 2 forces up. It's easier to make down positive and up negative, then you deal with less negative signs. That's why we always establish a coordinate system first, saying which sides will be up or down. In the end, our answer will indicate whether the resultant force is up or down, not whether it's positive or negative. I hope that makes sense.

If it's just 2 pieces, or easy to figure out in your mind, you only need to solve for one half, since you can figure out what comes next, they all have to come back to their return points on the graph. If you do enough questions, you can see what comes next without going through the steps. If you're new to this though, I think its better to solve for all the pieces :)

I have some questions about the last class. In the first example, when x=2 shows two separate regions, it is obvious that v is in the same direction. However, why are the regions of v different when drawing, one is 20 (the upper half axis of x) and the other is -10 (the lower half axis of x)? Is the final shape of the graph different for everyone (because everyone's initial assumptions are different)
@QuestionSolutions Жыл бұрын
we don't consider x = 2, we consider 0 =< x < 2, and 2 < x = 2, we have a shear force of -10. The difference between the two parts, so 20 - (-10) = 30 kN, that is the applied force of the beam. The diagram will look the same for every student, there shouldn't be any difference. There are no assumptions when drawing these diagrams.

@QuestionSolutions8 ай бұрын
So the 1200 N•m is an external moment applied to the beam. It's like someone randomly trying to turn it about that point. That needs to be accounted for in our graph. Clockwise means it needs to be added, counter-clockwise means it needs to be subtracted.

So we want these equations in terms of length. We don't want fixed values. A fixed value would only give us the shear force at a specific length, but if we write it with respect to "x" then we get it as a function of length.

And the 2nd one is, in the 2nd example when we are finding the moment about A, there is this moment 150kNm and it is positive, but why are the 320kN and 20kN forces positive and By is negative? I thought the By is gonna be positive since it is acting upwards and the 2 other forces are gonna be negative

For the first question, there are no x-forces acting upon the beam, so there isn't anything for us to consider. For the 2nd question, it depends on the direction you chose the moment to be positive. So for the 2nd example, we chose clockwise as positive. So looking at 6:16, look at the 320 kN force. It's pointing down, and imagine the beam is free to rotate about point A, which way would the beam rotate? If you push down at the location where the 320kN force is applied, it will turn clockwise about point A, so it's a positive moment. The same is true for 20 kN force. But look at the BY force. If you imagine using your finger to push up at that location, which way would the beam rotate? It would rotate counter clockwise, so it's a negative moment.

what do mean by finding the difference when you talk about the large jump in the shear force diagrams, a difference of what values. @ 16.46 to get 206.25
@QuestionSolutions Жыл бұрын
The timestamp you gave is incorrect, so I think you're talking about 9:06 because that's where I see the 206.25. If yes, then the difference is 20-(-186.25) = 206.25. So you're subtracting the bottom value from the top to figure out the difference between them.

How does sign convention work for moments? I thought at 12:05 that the moment be negative if it was clockwise.

at 7:46, why is it that it's -40x(x/2)? Shouldnt it be +40x(x/2) since the moment that the load causes is clockwise?
@QuestionSolutions5 ай бұрын
So when you're doing the segments, you're looking at it from the perspective of the cut (where the cut was made). So here, the 133.75 kN force pushes up, causing it to rotate clockwise but the 40x force pushes down, causing a counter-clockwise moment.

So, if I'm needing to find a generalized equation to demonstrate forces at any point along a beam, or cable, or some other rigid body, the moment and force diagrams are how you get there?
@QuestionSolutions9 ай бұрын
Hmm, I guess you can sort of say that, but simply put, shear force and moment diagrams are there to help us understand the effects happening on an object at any given point.

I have a question: When exactly is it absolutely necessary to split the beam into sections (i.e: using x for length, etc) when making shear/moment diagrams? Is there a way to tell which method to use when given a problem?
@QuestionSolutions Жыл бұрын
If you're referring to the 2 methods I show in this video, then you can do either one to get the same answer. Its faster to not split the beam and use method 2, especially when you become comfortable with the relationships between shear and moment diagrams.

Why are his moments positive in the clockwise direction? This is opposite of the right hand rule?
