Two acetyl plastic members are to be glued together and used to support the loading shown. If the allowable bending stress for the plastic is σ_allow = 13 ksi and the allowable shear stress is τ_allow = 4 ksi, determine the greatest load P that can be supported and specify the required shear stress capacity of the glue.
