Completely lost in Statics and this is literally the second homework

Click For Summary
SUMMARY

The discussion focuses on solving a statics homework problem involving angles and free body diagrams. The user calculated the angle between segments AB and BC as 18.43 degrees and the angle between segment AD and the axis as 33.69 degrees. The conversation emphasizes the importance of creating free body diagrams to visualize forces and moments acting on the system. Participants encourage the user to present their best attempt to facilitate further assistance.

PREREQUISITES
  • Understanding of basic statics concepts, including forces and moments.
  • Familiarity with free body diagrams and their construction.
  • Knowledge of coordinate systems in three-dimensional space.
  • Ability to calculate angles and apply trigonometric functions.
NEXT STEPS
  • Study the principles of free body diagram creation in statics.
  • Learn how to resolve forces into components using trigonometry.
  • Practice solving statics problems involving multiple bodies and angles.
  • Explore software tools for visualizing statics problems, such as AutoCAD or SolidWorks.
USEFUL FOR

Students studying engineering mechanics, particularly those focusing on statics, as well as educators and tutors assisting with homework in this subject area.

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.

Could you do free body diagrams for those problems?
