Homework Statement
A Solid rod with .375 in. D sits glued in the hole with .38 in. D. There is glue only on the annulus of the rod. A force is applied to the back side of the rod until the glue bond is fully sheared and the rod falls out.
Find the shear stress
Homework Equations
τ=F/A psi
Annulus A = π((D2/2)^2-(D1/2)^2) in^2
Force is observed values where the glue sheared in lbf
