In this video I will find the compression/tension and magnitude of a section of the members of a roof truss.
Next video in this series can be seen at:

Thank you sir, just one comment. I think it is easier to understand if when calculating the distance between Fch and the point E we use the sin of the angle between CD and CH. Of curse it is the same result, but I think we can understand it more easily if we draw it.

There are indeed multiple ways to solve this problem. 🙂

Sir by calculating the distance between Point H and Point E, we can use Pythagorean theorem right? Because there's 8m and 6m legs, and HE is 10 by computing Fch why I got 4.8 and its not 5 Sir?

That is correct.

Why is not the member HD considered for Force calculation at CH?

It depends on where the "cut" is made. Since the "cut" is made to the left of that beam, the HDE section is considered solid and doesn't affect the beams that are "cut".

it's structural engineering-- a part of civil engineering

You could say that. (There are common topics between mechanical engineering, structural engineering, and civil engineering.)

Typically you start at the end and then work inwards.

How does the distance CE multiplied by cos(theta) give the perpendicular distance?

Same question, is the perpendicular distance not 10 m, (8^2+6^2)^0.5 or 8/cos(36.9)

I stand corrected, 9.6m is correct as it´s the perpendicular distance. Autocad proved this to me, not my bad Math skills.
