It is not actually tensile but Compressive forces that main holes suffers, another type of stresses that it may suffer is hoop stress that is specific to curved surfaces and is present is the outlined curve of the body. (Details of hoop stress is beyond the scope of this thread, any one interested may google the topic or consult Text Book of Machine Design by Khurmi & Guptta or Elements of Machine Design by Shiglay.
