Calculating Moments Using the Method of Joints: A Tutorial

[chetzread]

I'm not sure if there's a hard and fast rule.
Seeing the quickest and easiest approach will come with practice.
This particular problem could be solved much faster with the method of joints.

I am not concerned about the speed of solving the question...
So, if we can't solve the question by moment about B = Cy(0.8) +Ay(0.8)
+ Cx(0.6) = 0
We have to choose to consider moment about a point in 1 force member only?

Can you show how do you solve the question by method of joints?

Best to wait until after you've learned the method in class.
