Thanks very much for this it has really helped me to understand this ❤❤❤

You are welcome! I am glad you found it helpful

THANK YOU !

How did you get 300N/m cause after using similar triangles that is supposed to be 200N/m

10/10 video

Still great videos to this day

Glad you like them! Thanks for your comment

how do you determine the distance from Fr1 and Fr2 from b ? i dont really get this part

[@engineeringvision]

Good question! For a rectangle, it is in the middle and for a triangular load, the resultant force is acting 1/3 of the base from the right angle of the triangle.

Excuse me, I'd like to ask, what do we do if the length of point C from either point A or B is unknown?

[@engineeringvision]

Then you need to have other information available

How did you figure out the 100 for the triangle when you cut the beam?

[@godfreymutale4876]

Using similarities of triangles, before it was cut the bigger triangle had 200N/m, after it was cut the smaller triangle was exactly half of the bigger one, finding the ratio(i.e 200:x=6:3) , x= 100. Note that 6 and 3 are just the base distances of a bigger and smaller triangles respectively.
