Hello all, I'm having a massive brain malfunction and am having problems calculating the tonnage for a cylinder shaped part (think a cup). It's 2mm thick, 250mm tall, and about 130mm in diameter (my kind of "beverage" cup!). I calculated the area (if it was a solid cylinder) and then subtracted the area of the core but it just seems too low. Any tips?

Also, I'm browsing the forum right now looking for similar questions but just haven't stumbled upon it yet.

Thank you!

MM
