Engineering Completely lost in Statics and this is literally the second homework

AI Thread Summary
The discussion revolves around a student's confusion with a statics homework problem, specifically regarding angles and coordinate axes. The student has calculated the angles between segments AB and BC as well as the angle between AD and the axis but is unsure how to proceed. There is a suggestion for the student to create free body diagrams to better visualize the problem. The importance of showing their best attempt is emphasized to facilitate assistance. Clarifying these concepts is crucial for understanding statics.

Homework Statement
I need help with questions 3 5 and 6 I managed to figure out the other three but I don't even know where to begin with these.
Relevant Equations
I know I need moment but that about it
For problem 3 I managed to get the angles between AB and BC and divided by 2 it ends up being 18.43. The angle between AD and the axis is 33.69 but I'm not sure what to do after that point. I have going from A to that cross as the Z axis and then y going up and x going parallel to the box.

Welcome!
We need you to show your best attempt.
Could you do free body diagrams for those problems?

Thread 'Have I solved this structural engineering equation correctly?'

Hi all, I have a structural engineering book from 1979. I am trying to follow it as best as I can. I have come to a formula that calculates the rotations in radians at the rigid joint that requires an iterative procedure. This equation comes in the form of: $$ x_i = \frac {Q_ih_i + Q_{i+1}h_{i+1}}{4K} + \frac {C}{K}x_{i-1} + \frac {C}{K}x_{i+1} $$ Where: ## Q ## is the horizontal storey shear ## h ## is the storey height ## K = (6G_i + C_i + C_{i+1}) ## ## G = \frac {I_g}{h} ## ## C...
