Bending Deflection at Given Points

Click For Summary

Discussion Overview

The discussion revolves around calculating beam deflection at specific points along a beam when weights are applied at different locations. Participants are seeking assistance with the equations and methods for determining deflection at these points, particularly in a scenario where multiple weights are applied.

Discussion Character

  • Homework-related
  • Mathematical reasoning

Main Points Raised

  • One participant expresses the need to calculate deflection at two specific points (0.5m and 0.75m) on a 1m beam when weights are applied at these positions.
  • They mention applying a weight at position one and measuring deflection at position two, as well as applying a weight at position two and measuring deflection at the same point.
  • Another scenario discussed involves applying equal weights to both positions and finding the deflection at both points.
  • Several posts reiterate the same questions and requests for help, indicating a desire for guidance on the equations involved.
  • One participant shares a link to a resource that may provide relevant information on beam equations.

Areas of Agreement / Disagreement

There is no consensus reached in the discussion, as participants repeatedly ask for help without providing definitive answers or solutions to the posed problems.

Contextual Notes

The discussion lacks specific details on the assumptions or conditions under which the deflection calculations should be made, and the mathematical steps involved in deriving the equations remain unresolved.

Beam Deflection

I am trying to calculate beam deflection for a number of points?

I know the formula for maximum deflection, but i need to calculate the deflection when.

Lengh = 1m
Possition 1 = 0.5m
Possition 2 = 0.75m

- I apply a weight to possition one, and need to measure deflection at point 2.

- I apply a weight to possition two, and need to find deflection at point 2.

- I apple weights to both possition 1 and 2 (equal) and find deflection at 1 and 2.

If anyone can help me, or demonstrate how these equations are found, or just point me in some direction, i would appreciate it heaps...
