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 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
