Hi There, 

I have looked through the forum before in relation to this question and seems like a few people have the same issue. I would like a fresh set of eyes to have a look at my model to find out what i am doing wrong. I am doing the CSWP practice exam paper, flew through Q1-3 and now that i am on 4 and 5 i am getting answers 10g short. I have gone over every dimension several times and checked the equations and material numerous times but still keep getting the wrong answer. If anyone could help that would be great. 

These are the conditions and drawing of the part to be made, i have attached my model. If someone could give me an idea of where im going wrong that would be great.
