THATS AMAZIG. Please keep going. The german engeneer static videos are very dry and dont use numbers. That's why I am looking for english videos, and yours is just perfect. Thank you!

Awesome! Glad I could help!

thanks for the great explanation I will use this channel and shared with some of my current classmates.

[@Professor_Engineer]

Great, hope my channel helps everyone!

Why didn't you include the gravitational force on 300? Is it just a choice? Does including it just change the unit such as newtons?

Thank you so much

No problem!

aren’t the angles wrong? shouldn’t it be 90-20 and 90-40

[@Professor_Engineer]

The angles shown are correct. And hopefully this explanation helps, think of the cable as a transversal line going through the solid black horizontal line at point A where the 40 degrees is measured and going through the x-axis at point C where I drew the free body diagram. Because that solid horizontal line and the x-axis on the FBD are parallel to each other, any line crossing both of these parallel lines will be transversal. Thus, the angle between the parallel line and the transversal line (on the interior side of the crossing) will be equal at each end. Basically, if the line of the cable is 40 degrees of the horizontal at one location, it will be that same 40 degrees off the horizontal at another location. If you need a better explanation, let me know. Hopefully this helped.
