first of all thanks for the beautiful explanation, but I have a question, why'd you multiply the horizontal component of F3 with 4? shouldn't the perpendicular distance from point A to Fx be 5 as well? or is every point along the horizontal part of the pipe considered as point A? (in the 1st problem)
@QuestionSolutions7 күн бұрын
So you can actually draw two lines at point A (perpendicular to each other like a coordinate system), extending towards the edges of your page. Then it's easier to see the perpendicular distances better. So for Fx, we are looking to see the distance towards the horizontal line, which is just 4m.

You can pick either direction, it makes no difference as long as you follow through with your positive and negative signs. So for example, assume you picked counterclockwise to be positive, then if you get a negative answer, the moment is clockwise. If you picked clockwise to be positive and you got a negative answer, then the moment is counterclockwise. If you picked counterclockwise to be positive and you got a positive answer, then the moment is counterclockwise. Lastly, if you picked clockwise to be positive and your answer is positive, then it is clockwise.

@QuestionSolutions4 ай бұрын
You can take it from O to A, and you will get the same answer. There will be no difference. You most likely wrote down an incorrect position vector. The position vector OA would be 3i+3j+0k. Keep in mind that there is already typo in the solution for that question as mentioned in the pinned comment. The answer for that problem is -128.34i+128.34j-256.68k. Whether you use a position vector from O to C or O to A, you will get the same answer.

@QuestionSolutions10 ай бұрын
@@Hussain-e9zokay, I see. For future questions, please use timestamps so it's easier for me to find. So in this question, it's not really a transfer of forces. When a force is applied anywhere along the pipe, a moment is created about point B. You can visually see this if you break a force into components. For example, look at force FX. We can slide that force along the horizontal length of the pipe and it will create the same moment regardless. Why is that? That's because the moment created is only dependant on the magnitude of the force and the perpendicular distance. In this case, it's 0.9m. Now look at FY, the perpendicular distance is 0.7m. For the second part of your question, the pipe will rotate clockwise. Imagine the pipe is free to rotate about point A and you push at point B towards the left. Then we can see it would start spinning clockwise.

Hi, i thought clockwise direction was negative and counterclockwise was positive or it doesn't matter?

Sorry, I don't solve questions like this because then I have to solve everyone's problems 😅 I encourage you to use math/physics forums if you need help with a specific question.

At 5:47, why can't you just split the force into its x and y components and then solve the question like the previous two?
@QuestionSolutions6 ай бұрын
Excellent question! This is a 3D problem, that means the force now has x, y and z components. You cannot break it into components the same way you did with 2D problems. So you have the express that force as a cartesian vector, in other words, we must express the 80 N force in it's x, y, and z components, and then take the cross product to find the moment.

6:23 shouldn't 256.68 be a negative (-)? Since we alternate our operations in doing matrices + - + last term should be + [(4)(-64.17) - (0)(21.39)] which results to - 256.68. Please correct me if I'm wrong.
