I have found the equation needed for this, I needed to search for an equation for a cantilever beam with an evenly distributed load, which looks like this (see added picture).
ω = load in Newtons pr. m
l = length of the affectd area
E = is the elasticity of the beam (something that you need to look up)
i = is the inertia of the affected axis (in this case the x-axis, this is found by this formula 1/12*width of the beam*height of the beam³, to find the y-axis inertia simply switch the positions of the height, and width)
