Force DF should be under tension, not compression like you wrote

Can I ask why didn't you use the equations of equilibrium? With those equations you are able to use previously taught concepts throughout the Hibbler textbook and continue to build off of each other. I'm just trying to understand your perspective/thought process on why you decided to approach this problem this way. Thank you for taking the time to work through this problem.

Awesome vid, really helped me understand working with trusses

Around 3 minutes in when solving AB, why was 130*(5/13) positive. Because of the way the 130 lb force is pointing, shouldn't it be negative?

7:02 I still dont get why 150 x 3/5 multiplied by two

[adambomb]

Compression is (-) and tension is (+).

How to figure out the direction of forces? I am kind of Confused.
