Deflection in a Cantilever beam

AI Thread Summary
To reduce deflection in a cantilever beam with a fixed end and a load at the free end, several strategies can be employed. Key methods include reducing the beam's length, increasing its modulus of elasticity, and enhancing the second moment of area. Additional support structures, such as cables or stays, can also be considered, although their effectiveness may vary based on design. Modifying the beam's structure can potentially minimize deflection to near zero. Understanding the relevant formulas and variables is crucial for effective design adjustments.

Hello,

i was looking for ways i can reduce the deflection in the cantilever beam whose one end is fixed and load is applied at the free end.

Few i thought of was,
1- Reducing the length of the beam
2- Increasing the modulus of elasticity of the beam
3- ??
4- ??
5......

Appreciate your help

Thanks

One of few formulas you should memorize is the deflection at the free end of a cantilever with a point load applied at the free end. Write it down and see what variables you can change besides length and elasticity yo reduce the deflection.
 
Increasing the second moment of area of the beam, providing extra supports etc.

I'm trying to reduce the reflection of a cantilever beam as well, but there isn't much you can do. Best bet is to reduce the length but in most cases it isn't possible.

Can you use a supporting cable to help?

Optimised variable section .
Rigid stay .
Haunch .

Cable stay shown is not set at a very effective angle to reduce deflection .
Cable stays with no provision for setting tension are in any case not a reliable means of reducing cantilever beam deflection .

Edit : Old thread - op has gone .

The deflection can be made approximately zero by creation/modification of the structure in that way.
Then the arrangement of members will form a structure which deflects the point to some other direction or make it zero approx...
 
How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
