Dear Chet,
The equations provided by you fully sums up the idea
So the dilemma I have is which one of these approaches is correct?
Is there a reason I can't substitute both side forces by one?
Ok, I've gathered everything in my picture (see link).
The first part is how I calculate shear stress out of side force (how I get the formula)
The second part - two approaches to finding shear stress at point A.
Why the results are different and WHY?
If even this doesn't clarify my question, I...
My problem is more complicated - it has all bunch of load (bending, torsion, compression/tension) and I have to find the critical point (where crack will appear) and calculate stress at this point.
But I don't want to complicate things - the problem is exactly as I mentioned above.

Dear Chet,
Ok, I'll simplify the problem.
You have a beam fixed with one end to the ground with a cross section along the beam of a circle with a radius r = 1 m
There are two forces acting at the free end of the beam perpendicular to the length of the beam Qx = Qy = 200 N (end perpendicular...
Ok, Here's everything in detail.
Please find attached shear stress distribution along Y axis due to side force Qy (don't pay attention to blue arrows yet)
Based on this, there is a shear stress τx acting on the line (marked red).
Point A (see previous pictures) belongs to this line, therefore if...
Ok, just found this might fall under "unsymmetrical bending", when bending moment and shear force is not acting along principal axis.
In this case It's suggested that moment (presumably shear force as well) should be split into two components acting along principal axis and both cases should...
Yes, forgot to mention, in my case Qx = Qy.
The shear force (say Qx) is a sum (integral) of all distributed shear stresses in the section in this (x) direction.
The distributions of these shear stresses is as follows - max in the centre and 0 in the furthest point of cross section along...
Dear Colleagues,
This problem causes me a headache - any suggestions?
I have a truncated cone under bending on two axes.
I take a section where I have two acting side forces - Qx & Qy
I want to find shear stresses acting in the point A which is on a circumstance of the section 45° between axes...
