Deflection in a Cantilever beam

Click For Summary
SUMMARY

The discussion focuses on methods to reduce deflection in a cantilever beam with a fixed end and a load applied at the free end. Key strategies identified include reducing the beam length, increasing the modulus of elasticity, and enhancing the second moment of area. Additional suggestions involve using supporting cables and optimizing structural design to minimize deflection. The conversation emphasizes that while some methods may be limited, structural modifications can effectively address deflection issues.

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...
