Help with beam deflection problem

Click For Summary

Discussion Overview

The discussion revolves around a beam deflection problem presented by a participant who is struggling to read handwritten notes and formulas from a textbook. The focus is on understanding how to analyze forces and moments acting on the beam, as well as how to create a free body diagram to aid in solving the problem.

Discussion Character

  • Homework-related
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant expresses frustration over unreadable handwritten notes and requests help with the beam deflection problem.
  • Another participant suggests starting with determining all forces and moments acting on the beam and drawing a free body diagram.
  • A participant indicates difficulty in identifying specific values needed for the free body diagram due to the unreadable text.
  • There is a suggestion to replace two loads on the beam with a single load and moment for simplification.
  • A participant asks how to determine the load's position between two points and what formula to use after creating the diagram, citing unreadability of the relevant chart.
  • One participant provides specific locations for the loads (240 lbs and 80 lbs) and hints that knowledge from a statics class should suffice for finding an equivalent force and couple without needing formulas.

Areas of Agreement / Disagreement

Participants generally agree on the need to create a free body diagram and analyze the forces acting on the beam. However, there is disagreement regarding the specific values and formulas needed, as well as the participant's ability to read the necessary information from the textbook.

Contextual Notes

Limitations include the participant's inability to read handwritten notes, which affects their understanding of the problem and the formulas required for analysis. There is also a lack of clarity on the exact placement of loads and the corresponding calculations.

I need help with this beam deflection problem for 1 the book my professor gave me almost everything is hand written including the beam stuff... SO I can't read it at all and its really frustrating trynna do this without being able to read the formulas or anything please helpp! I attached the problem please link whatever formula you used ty!

What about statics? Was everything in your statics class handwritten by the professor there?

In all beam problems, you first determine all the forces and moments acting on the beam, and you draw a free body diagram. Try this first, and then we'll see what else you need to know.
 
well I can't even read the top part to determine that where the 240 and 80 are to make the free body diagram. I need that and which formulas from the chart that I can't read
 
Show us your attempt and we'll go from there.

The first thing you should do is replace the two loads on the upper beam with a single load and moment on the lower beam.

As always, do free body diagrams.
 
well how do I do the load at the exact point between the 12 and 8? and what formula do I use after that I have the diagram except that value and the chart in my book for which formula I am supposed to use after that is completely unreadable.
 
and that was a screen shot from the book I have no way to take a picture off my paper
 
You have a load of 240 lbs. located 12" from the base of the T. You have another load of 80 lbs. located at 8" from the base of the T. If you wanted to find an equivalent force and couple acting on the beam, with which to replace these two loads acting on the T, how would you do it. Hint: you don't need formulas for this; you should have already learned how to do this in statics class.
