Thank you very much, this has really helped raise my confidence when approaching problems like this.
I had another go of it and I still don't understand the xy shear stress at point 1.
If it comes from the shear force Vy, wouldn't shear stress be 0 at point 1
The shear stress distribution is...
Looking at the base of the road, my 2 points are
so I got that..
Vy= -120N
Torque(Tx) = 120 x 0.125=15Nm(clockwise)
Bending moment (Mz)= 120 x 0.25= 30Nm
J = 2.03x10^-9
I =1.02x10^-9
Q=4.20x10^-7
At point 1, I think there will be no contribution from Vy to shear force acting on point 1
