Cantilever beam with curved beam on the end.

AI Thread Summary
Calculating the deflection of a cantilever beam with a curved beam at its end involves analyzing each section separately. The bending moment on the curved beam should be assessed while assuming the straight cantilever is fixed. After determining the displacement of the curved beam, the same bending moment is applied to the cantilever to find its displacement. However, simply adding the displacements of both beams does not yield an accurate result, as the cantilever's tip rotation also affects the curved beam's deflection. A more comprehensive approach is needed to account for the interaction between the two beams.

struggling to find info on this so figgured i'd as.

For two beams attached to each other, one a straight catilever and the second a 90 degree bent beam attached to the end of the cantilever (shown in attached picture). To calculate the deflection of the beam at the load applied, given the load applied is on the open face of the bend.

Would you consider each part seperatly?
so for the curved beam calculate the bending moment applied to that relative to the assumption that the straight part of the beam is fixed in position, then calculate its displacement.

Then apply the same bending moment to the canilever calculate its displacment.
To get the total displacement add the compenents of the cantilever and the bend together to get its final position?

That would not give you the right answer because the straight portion of the cantilever also rotates at its tip causing an additional rotation and deflection of the curved portion.
 
Thread 'Where is my curb stop?'
My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter. Is that knob that I drew a red circle around my meter...
Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...
