Question: 5 . 8 - 1 0 A laminated plastic beam of square cross section is built up by gluing together three strips, each 1 0

5.8-10 A laminated plastic beam of square cross section is built up by gluing together three strips, each 10mm30mm in cross section (see figure). The beam has a total weight of 3.6N and is simply supported with span length L=360mm.
Considering the weight of the beam (q), calculate the maximum permissibe CCW moment M that may be placed at the right support.
a. The allowable shear stress in the glued joints is 0.3MPa.
b. The allowable bending stress in the plastic is 8MPa.
