Hi there I've got a task where i need to use manual calculations with this setup (see attach.) there is a cylinder with two internal grooves (yellow part). 5 Dogs are equally spaced (72deg.) inside that cylinder. They are being pushed by the Force against the grooves in the cylinder. What stresses i have to calculate to make sure the construction is stable with applied Force. And what equations I need to use. I guess is only shear stress, maybe a compression stress from 45deg angle, but someone is mentioned bearing stress as well. Is there any kind of stresses i should be looking at? Kind Regards, S.
