Shear stress in cross-section of a beam

a = 4 cm b = 1 cm
c = 1.257 cm d = 2 cm
f = 0.8cm = 1.305 cm4


If this cross-section is exposed to a shearforce is V(x) = 3000 N how big is the shear-stress at :
  1. the top of the beam, level 1, y=-0.743
  2. at the neutral axis, level 2, y=0
  3. just a tiny bit above the junction of web and flange, level 3, y=0.457
  4. just a tiny bit below the junction of web and flange, level 4, y=0.457
  5. At the bottom of the beam, level 5, y=1.257
