Undergrad Finding Maximum Strain with Cantilever Beam

Click For Summary
The discussion focuses on calculating the moment of inertia and maximum strain for a cantilever beam. The moment of inertia is identified as I = 1/12(b)(h^3), but the user struggles to find a suitable diagram for strain analysis. It is noted that the beam will experience a single force at a specific distance rather than a uniform load. Further clarification on the user's difficulties is requested to provide more targeted assistance. The conversation emphasizes the need for proper resources to visualize the strain on the beam.

Hello,

I am trying to establish what the moment of inertia is for this cantilever beam as well as the maximum strain.

General formals preferred.

Thank you

What have you done so far to try to find this information ?

A quick search should give you all the information you need .
 
I have found that the inertia is I = 1/12(b)(h^3). However I am having difficulty finding a proper diagram for the strain. There is not going to be a uniform force acting on the beam, but rather a single force at any distance (deltaL) on the beam.

If not then please try to explain what your difficulty is in more detail .

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
