How to find strain in simple cantilever beam

AI Thread Summary
To find strain in a rectangular cantilever beam under a point load, the relationship between stress and strain is crucial, as defined by Hooke's Law. The stress can be calculated as the applied force divided by the cross-sectional area of the beam. Strain is then determined by dividing the stress by the Young's modulus of the material. Specific formulas for cantilever beams can be found in resources like efunda.com, which provide detailed case studies. Understanding these principles is essential for accurate calculations in structural engineering.

Hello to everyone,
my question is how to find strain in rectangular cantilever beam applying point load at some point. I am not getting formulas for that..Please save me from this. Its very urgent for me.

Hi ashunitk, welcome to PF. Are you able to find the stress? Hooke's Law links stress and strain.
 
I am not cleared with wat u have given answer about how to find strain. Can u just send me formula to find strain of cantilever beam of rectangular cross section having point load at its free end with description of formula.
 
Ya what u said is right but that is general ..but i want specific to cantilever beam.As u said strain equals to stress by young's modulus.Where stress equals to force by area.can u send some document regarding to my mail id if so my id is zoom143.ashwin@gmail.com...
 

Thread 'Bubble formation in 4 mm gap vessel'

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...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

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...
