where are fixed beams used in real life? having real trouble googling them ad finding examples apart from buildings.

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
