I need help with this question that came up at a job interview.

I would like to ask this question from the Cylinder & Pressure Vessels topic in lesson Cylinders and Pressure Vessels and Design of IC Engine Components of Machine Design

Answer 1

Right answer is (b) Thick Cylinders

To make it clear: Smaller dia to thickness ratio implies more thickness and hence these are classified under thick cylinder.
