I'm confused, since the given diameters are in mm and the shear is Mpa, which is m². Don't you need to convert it first? Also 350M is 350x10⁶ right?

or you could use the lateral area of the cylinder which is 2*pi*r*h, where h is the thickness and change r to diameter where D = 2r, you'll get the same formula: pi*d*t

not to be mean, but I only know english, :/ it started okay
