    Hi, Macbarbicus, welcome to PF!

    Per forum rules, you are going to have list what you believe are the relevant equations, and show some attempt at your work, before we can be of assistance. You should be familiar with the shear flow formula which indicates how the shear stresses vary over the beam cross section.
