Discussion Overview

The discussion centers on the real-life applications of fixed beams, exploring examples and contexts in which they are utilized. Participants examine both fixed beams at one end and those fixed at both ends, considering their relevance in various structures and tools.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • Some participants suggest that fixed beams are commonly found in buildings and bridges, as well as in telescopic cranes and flagpoles.
  • One participant mentions that a fishing rod can be viewed as a fixed beam, being anchored at one end.
  • Fixed beams at both ends are discussed, with examples including walking bridges between buildings and sections of bridges located between supports.
  • There is a question raised about whether a connecting section between a cantilever bridge qualifies as a fixed beam.
  • Another participant describes how structural horizontal concrete and steel beams are solidly connected to columns, allowing for moment transfer without hinge effects.
  • A participant emphasizes the need for effort in identifying common types of beams and their applications in real life.

Areas of Agreement / Disagreement

Participants express differing views on the use of fixed beams in bridges, with some asserting that they are used while others question this assertion. The discussion remains unresolved regarding the classification and examples of fixed beams.

Contextual Notes

There are limitations in the discussion regarding the definitions of fixed beams and the assumptions about their applications in various structures. Some examples may depend on specific interpretations of what constitutes a fixed beam.

where are fixed beams used in real life? having real trouble googling them ad finding examples apart from buildings.
 
Physics news on Phys.org
If you mean fixed at one end, I gave you a couple of examples in your previous thread.
Many buildings use the concept.
The cross section of many bridges use the concept.
Telescopic cranes use the concept.
Flag's poles use that concept.

A fishing rod is just that, fixed to the hand of the fisherman; same for most tools, pens, etc.
Anything that is more or less horizontal and is not supported at both extremes in order to avoid falling, could be considered a fixed beam.

If you mean fixed at both ends, then we can find more examples:
A walking bridge between two buildings.
The section of any bridge that is located between two contiguos supports.
Pipe supports anchored to two columns.
Structure of steel buildings.

fixed at both ends (encastre beams)
i thought bridges didnt uses fixed beams.

for 'The section of any bridge that is located between two contiguos supports' would a connecting section between a cantilever bridge be one.

the fixed at both ends beams do you have any other that i can write about

Sorry, I am unable to post pictures today.
Normally, structural horizontal concrete beams for buildings are solidly connected to columns supporting their ends by continuation of internal rebars.
Also, structural horizontal steel beams that run between two concrete walls, two concrete columns or two steel elements of the structure are solidly connected to those via anchors, bolts, welds, etc., in such a way that moments can be transfer from the beam to the other element (there is no hinge effect).

Since this is your schoolwork, you need to show lots of effort in answering your question. Can you list the most common types of beams and beam supports, and say when they are used? From that list and your summaries, can you say where in "real life" applications each would be the most applicable? Thanks.
 
thanks all.
ive google thoses ideas and going write about them
