Solve Structural Mechanics Qs 3 & 6 on PDF Files

Click For Summary

Discussion Overview

The discussion revolves around solving specific structural mechanics questions from attached PDF files, specifically questions 3 and 6. The focus includes the application of formulas and the interpretation of problem statements in the context of structural mechanics.

Discussion Character

  • Homework-related, Technical explanation

Main Points Raised

  • One participant requests solutions for questions 3 and 6 from the PDF files.
  • Another participant advises that solutions should not be provided directly, suggesting that showing work may lead to helpful tips.
  • A participant discusses the need to revisit the derivation of the equation for horizontal shear stress for question 6, indicating that adaptation of the equation may be necessary and emphasizing the importance of understanding the forces and stresses involved.
  • Regarding question 3, a participant expresses ambiguity, suggesting that it could refer to a section measurement or be interpreted as a punching shear problem, indicating multiple interpretations of the question.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the interpretation of question 3, with differing views on its meaning and approach. The discussion remains unresolved regarding the specific solutions to the questions.

Contextual Notes

There are limitations in the clarity of question 3, with assumptions about the interpretation of dimensions and the nature of the problem not fully established. The necessity for adaptation of formulas in question 6 is also noted but not resolved.

Hi darius2626, welcome to PF. People won't solve problems for you here, but if you show your work, you'll likely get helpful tips.
 
For question 6, there is a formula, but I would recommend that you go back to the derivation of the equation for horizontal shear stress, so that that you can 'feel' the forces and stresses. That equation will need adaptation for the case you have got, and I would suggest you look carefully at the units required for a clue on how to do it.
Question 3 looks ambiguous to me. It probably means a section 2.5 x 0.5 but could also be interpreted as a punching shear problem with an area 4x2x0.5 x 0.5 deep (that is a rectangular blob around the column being forced through the slab ( a bit like when you punch holes in file paper).
 
thanks for your time and guidance.
