Why?

asylum15 · Answer

Just wondering why you asked :)

asylum15 · Answer

Any idea how to solve ? :|

asylum15 · Answer

I've done numerous questions like these, but never been given 2 variables where one is load.

Do you have an idea how you will do it ?

asylum15 · Answer

Nah, it's so different to Qs I've done previously.

It's one out of 100 i can't do :(

mathmate · Answer

First find the bending moment at the support of the cantilever:
M=PL  (L=length of cantilever, and also distance from load P to the support)
$ \sigma_{max} = My/I$
where I=area moment of the cross section
y=maximum distance from the neutral axis = radius of the cantilever.

What you will have calculated will be in terms of L (length of cantilever) since it is not given.

By the way, this question belongs to structural or mechanical engineering.
