I'm not suggesting anything at this point. I'm just trying to understand what it is you're looking for.Ben9622111222 said:Yes. I am doing vibration analysis. Do you suggest pinned arrangement instead?
Ben9622111222 said:Kk.. Please have a look ath the link below

You can see, that the initial conditions here are easy enough to get and also proceed forward. In my case its not, due to the overhanging section
I am trying to make an equation like equation 10 in the above link for my system.
You need to 'model' the beam.Ben9622111222 said:No there is no forced vibration. The rod is flexible, and it is rotated by a motor. the motor position is the clamped support shown. So when the rotation stops there will vibration at the tip. to modal this, I need to find the beam boundary conditions.
Beam boundary conditions refer to the constraints or limitations placed on a beam structure at its ends or supports. These conditions dictate the behavior of the beam and affect its overall stability and strength.
There are four main types of beam boundary conditions: simply supported, cantilever, fixed, and continuous. Simply supported beams have supports at both ends that allow for rotation and movement of the beam. Cantilever beams have one end fixed and the other end free to move. Fixed beams have both ends fixed, which restricts rotation and movement. Continuous beams have more than two supports and are often used for longer spans.
Beam boundary conditions play a crucial role in determining the forces, stresses, and deflections in a beam. Different boundary conditions will result in different load distributions and structural responses. Therefore, it is important to accurately determine and consider the boundary conditions when analyzing a beam structure.
The selection of beam boundary conditions depends on several factors, such as the type of load applied, the material properties of the beam, the span of the beam, and the desired level of stability and strength. Other factors, such as cost and construction limitations, may also influence the choice of boundary conditions.
In most cases, beam boundary conditions are determined and designed before construction begins. However, in some situations, it is possible to modify or change the boundary conditions after the beam has been built. This may require additional structural support or reinforcement to ensure the stability and safety of the beam.
