Tbh this method was the only method that really helped me understand problems with negative slope. I tried doing the section method calculating the moment and vertical force with respect to x and couldn’t find a solution. With this method it was so straight forward. Thanks for the help.

you are gorgeus sir. my old man professor know anything or he is very selfish and greedy. whatever, It helps when information is shared. No one is trying to reinvent gravity to understand quantum physics. But university professors sometimes have the opposite idea. Thank you for your very clear and unambiguous explanation.

Thank you for this! My professor told me something really weird about this type of situation with the triangle. Usually the triangles start at zero on the very left, then go up. I think when the professor saw it this way, he got himself confused and solved it a completely different way. Now, I see that he was wrong. I plan on talking to him soon. Again, thank you!

Thanks for posting such a helpful information. Q: why did you come up with positive slope in load equation W(x)=1/2x-3? As you mentioned, the line in the problem is going down and slope should be negative. please correct me if I'm wrong. Thanks

@studentengineering Жыл бұрын

Great question! The way it is drawn it is a negative slope but if you draw negative forces below the line then that hypotenuse of the load triangle becomes a positive slope. Doing it that way makes all the equations work out better. I explain that more in this video: kzfaq.info/get/bejne/mNBondmLm6mcnGg.html Hope this helps!

The curve must be outward on the shear diagram right? Since the triangular load is sloping downwards?

@studentengineering 3 жыл бұрын

That would be correct if the load was sloped downwards but I explain in the video why it is actually sloped upwards. I also explain it even better in this video: kzfaq.info/get/bejne/mNBondmLm6mcnGg.html

I don't understand from first step due to -6.75 and-9.2 from were you have get them from And :Ay+105-9.6 were you also got them from, please help me

@studentengineering 10 ай бұрын

Good question! In that step I am summing moments about a point. A moment is a force times by a distance. The 6 is the force and the 7.5 is the distance. Same with the 9 times by 2. Here’s a couple of videos that explain moments and equilibrium equations in more detail: kzfaq.info/get/bejne/hq5hZr1zzJuxkZ8.htmlsi=te31Lzf3g0hoFAhn kzfaq.info/get/bejne/ntVibNhknbXHj2g.htmlsi=oe7UuM-wO8mHRJOs Does that help?

I tried setting the moment equal to 0 to get the distance where it crosses the axis but I got 0. How did you get 3.8? I think I made a mistake.

@studentengineering 2 жыл бұрын

Great question. I guess I couldn’t tell you why you didn’t get 3.8 but 0 is also an intercept for that equation because we know the moment is 0 when x=0 so you didn’t necessarily get the wrong answer. Use that moment equation that I came up with in the video and then set it equal to zero and solve for x. Since it is a third order equation you will get three values for the intercepts. One will be 0, one will be 3.8 and another one will be something else that would be outside the range of where we are using the equation (less than 0 or greater than 6). I would recommend using Wolfram Alpha or Symbolab solve for those intercepts for you.

HOW DID YOU GET 3.8m ON THE SHEAR DIAGRAM?

@studentengineering Жыл бұрын

Great question! You need to create an equation for the force on the beam and then you integrate that equation to get the shear equation. Once you have the shear equation you set it equal to zero and solve for the variable (x in this case) to get where along the beam the shear is zero. Does that make sense?

Where does 1.76 came from

@studentengineering 2 жыл бұрын

Great question! It comes from setting the shear equation equal to zero and solving for x. I do that in the video at 8:10 kzfaq.info/get/bejne/n9N8iJaAnJ-VgIU.html Let me know if you have any more questions!

where 3.8m came from on BMD

@studentengineering 3 жыл бұрын

We set the moment function equal to zero and solve for x to find out where the bending moment diagram crosses the axis and when we do that we find that the bending moment is 0 at 3.8 meters along the beam.
