Homework Help Overview

The discussion revolves around calculating the strength of empty beer or soda cans for a project involving furniture making. The original poster mentions that the cans can hold around 52 kg based on experimental results but seeks a formulaic approach to determine this strength, particularly considering the can's shape.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants explore the possibility of calculating the strength based on wall thickness and shape, with references to hollow tube formulas. There are questions about whether the weight capacity of multiple cans can be additive when arranged in a square formation.

Discussion Status

The discussion is ongoing, with participants seeking clarification on the calculations and exploring different interpretations of the problem. Some guidance has been offered regarding the terminology used in the thread title.

Contextual Notes

Participants note that the cans are empty, which may influence the calculations. There is also a mention of the need for complete information in the original post for clarity.

Homework Statement


I am doing a project which involves making furniture out of beer/soda cans but I need to do some calculations for it.
I know the can can hold around 52 Kg or even more based on experimental results but is there any way to find out with some formulas?
I found it tricky because of the shape of the can...

Edit: The cans are empty.

What question are you asking?

What have you tried?
 
I am asking if there is any way to calculate the strength of a empty beer / soda can based on the thickness of the wall or shape or something.

I tried looking for formulas for hollow tubes because I thought it would be similar but I couldn't get anything.

If there is no solution to this, I can consider for example that the can is a cylinder which can hold 50kg and add more cylinders next to each other in a square shape and try to determine the distributed weight they can all hold. Does the weight it can hold stack with each cylinder I add, like two cylinders can hold 100kg since one holds 50kg?
Are there any calculations I can do for that?

The title of the thread has the word "resistance". Strength would be a better word. Also, I see that you're new here: You should always include all pertinent information in the body of the Original Post of a tread, no matter what is included in the title.

By the way; Welcome to PF !

Alright, thank you for the info. :D
