Extracted text: 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 N and is simply supported with span length L = 300 mm. 10 mm 10 mm 30 mm 10 mm 30 mm Considering the weight of the beam (9) calculate the maximum permissible CCW moment M that may be placed at the right support. (a) If the allowable shear stress in the glued joints is 0.5 MPa. Round to the nearest tenth. Mmax =| N.m (b) If the allowable bending stress in the plastic is 8 MPa. Round to the nearest hundredth. Mmax =| N. m
