I was working the NCEES Mechanical sample questions, machine design depth number 528. In the solution, they used a safety factor of 2, but no safety factor was specified in the problem.
In the exam, are we to assume a safety factor of 2 when asked the minimum thickness of shafts, etc.?
Also, can anyone confirm the cross sectional area of a 1/2"-13 UNC bolt is .142 in^2? They used that value foe problem 524, and I can't find that anywhere.
