Load distribution on frying pan

[A_Little_Lost]

Hey,

i am an undergrad student studyn eng. i was given a materials assignment in which we have to pick an object made out of two or more dominant materials. i chose to do a frying pan that has a pan made out of aluminium and the handle made from bakelite (phenol formaldehyde). one of the things we have to find is the maximum load the pan can take before failing. i have information such as young's mudulus, tensile/compressive strength at failure, density. i figured that the pan acts as a cantilever, with the handle acting as the 'beam', the pan and applied loads acting as the 'point load at the tip of the beam' and our arm acting as the 'fixed end support' (meaning when we lift it). i have no idea how to find the maximum load, since i can't really find a change in length after loading nor can i find the yield strength of bakelite ANYWHERE! is there any other way i can find it? please help!

Thanks!

If you are just in materials, what you're trying to do seems a little beyond what you should know at this point. There are going to be several possible failure mechanisms for the description you have. First, there is shear through the bottom of the pan (certainly not going to happen). The handle could also fail by shear (also not going to happen). The most probably failure point is where the handle meets the pan. You will have a combined loading at that point (both shear and normal stress from the moment). Then, it depends on how the handle is attached (screws, welded, etc).

Here are some phenolic rubber properties from Matweb.

One can also search on trade name - http://www.matweb.com/search/SearchTradeName.asp

or just go and browse - http://www.matweb.com


However, it's perhaps best to find a textbook in materials in order to get some properties and additional information.

Bakelite is a trade name from the old Bakelite Corporation, which is now part of Hexion Specialty Chemicals.
