From the figures given below, identify the correct shear diagram and determine the maximum absolute value of the shear. For the beam and loading shown, design the cross section of the beam, knowing that the grade of timber used has an allowable normal stress of $11\mathrm{.}5$ MPa. $($Round the final answer to the nearest whole number.$)$

The height $\backslash ($ h $\backslash )$ of the beam is mm $.$
