CSWPCDES sample exam

ben,
where can i get the sample exam to see whats the question?

ben, you have calculated Ry but forgotten to include x component of reaction force at R (i mean Rx). if you equate the total force on x axis to zero, that leaves Rx=F*cos45=7.07 and the total reaction force is R=(Rx^2+Ry^2)^.5=(2.02^2+7.07^2)^.5=7.35

oh sorry ben, i thought you mentioned Q5!!
well if you consider this as a simple single axis stress problem, your answer is correct but here it mentions that the cylinder has a decrese in diameter. so you cant consider this as a single axis stress problem and use the simplified hooks law. you have to use the generalized hook's law (multiaxial) in cylindrical coordinate system which considers both radial and longitudinal strain. since i haven't used it for a while i can't seem to apply this correctly. so i'll check later and give you a feedback.
