Question

A laminated plastic beam of square cross section is built up by gluing together three strips, each 10 mm x 30 mm in cross section (see figure). The beam has a total weight of 3.6 N and is simply supported with span length L = 360 mm.

Considering the weight of the beam (q), calculate the maximum permissible CCW moment M that may be placed at the right support.
a. The allowable shear stress in the glued joints is 0.3 MPa.
b. The allowable bending stress in the plastic is 8 MPa
