The Method of Joints (support reactions)

AI Thread Summary
The discussion focuses on the method of joints for analyzing force members in a truss, specifically regarding support reactions. The user initially seeks clarification on whether to include Force Dx when calculating the moment around support reaction E. Additionally, there is a question about the presence of a force in the Ex direction when determining forces in the X direction. Ultimately, the user resolves their confusion independently. The thread highlights common challenges faced when applying the method of joints in structural analysis.

So, I have a question regarding the method of joints used to solve force members in a truss. I am just starting the question and I am stuck on determining the moment in the support reactions.

So my questions are:

(1) For the moment around support reaction E do I include Force Dx in my equation?
So, [+Dx * 5]

(2) When finding the forces in the X direction is there a force in the Ex direction?

Thank you.

Thread 'Is there a white hole inside every black hole?'

This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy out continuously The mass/energy that is spit out of a white hole drops back into it eventually. This is because of extreme space time curvature around the white hole Ironically this extreme space time curvature of the space around a white hole is caused by the huge mass/energy packed in the white hole Because of continuously spitting mass/energy which keeps...

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
