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). M 9 110 mm 110 mm 30 mm 110 mm 30 mm The beam has a total weight of 3.7 N and is simply supported with span length L = 260 mm. (a) Considering the weight of the beam (9), calculate the maximum permissible ccw moment M in N·m) that may be placed at the right support if the allowable shear stress in the glued joints is 0.3 MPa.
