30 mm 200 mm 30 mm The wooden T-beam shown in Fig. 11-9a is made from two 200 mm x 30mm boards. If allow 12 MPa and Tallow = 0.8 MPa, determine if the beam can safely support the loading shown. Also, specify the maximum spacing of nails needed to hold the two boards together if each nail can safely resist 1.50 kN in shear. B 200 mm 1.5 kN 0.5 kN/m C 2 m -2 m (a) D
