Exercise $4$

A timber frame is shown in Figure $4\mathrm{.}1$ below. Determine the required minimum thickness $t$ of member $AB$ and edge distance $b$ of the frame if $P=38kN$ and the factor of safety against failure is $2.$ The timber has a normal failure stress of ${}_{\text{f}\text{a}\text{u}\text{l}}=40$MPa, and shear failure stress of ${}_{\text{f}\text{a}\text{u}\text{l}}=10$MPa.
