The profile whose cross$-$section is shown in the figure was obtained by gluing rectangular$-$section flat wooden plents with glue. Since the shear safety stress of wood and glue are Twood $=4$MPa and $T_{\text{g}\text{l}\text{u}\text{e}}=3$MPa, respectively. calculate the largest shear force $T_y$ that the section can safely carry.Draw the stress diagram for this situation.

$a=(150+a)mm$

$b=(120+)mm$

$d=(150+)mm$

$t_w=(10+a)mm$

$t_f=1\mathrm{.}5tw$
