Hi all, this is my first post and i am learning for the CSWA exam.

I am making sure that in each question i solve i am dead on the correct numbers.

I encounter a question from 2013 exam (modeling a wheel) and in that question i have a 0.3 grams difference in the part mass.

Correct answer: 3198.58 grams

My answer: 3198.88 grams

Further investigation shows that that the extruded cut thru the sides of the wheel is the section with the difference its a 0.01g * 30 times (15 in each side) = 0.3g

I am uploading the following:

1) The test that i found online (This is Question 7)

2) My solidworks file (Q7.SLDPRT)

3) A solution downloaded with the exam, in that solution he got the correct answer (SolidModel2-Correct.SLDPRT)

I did everything i could. I spent hours on measuring and double checking everything and would greatly appreciate someone help.

Thank you

Tom
