I should appreciate it if you would show it in any of my examples. I really have no idea. Torque free hinge in statics.

I agree that they will turn if we separate them free. When two opposite motors give opposite torques to the connected rod, the rod does...

Yes, my black point means hard fixed for an example by welding. I am not familiar with torque-free hinges. By replacing welding with...

We divide the system into two sub-systems: the horizontal rod (HR) and the diagonal rod (DR), such that the total external force on each...

I consider three cases shown below, in which one of the three points of the jig is either x-free or y-free. In cases (a) and (b), one...

So anyway the screw undertakes larger torsion caused by larger upward force from the jig in the smaller angle case, right?

The jig would undertake a big torsion and the screw to attach the jig to the wall would break by the large upward force’s torsion, right?

For small angle the large downward force at the wall contact point and the large upward force at the diagonal rod point both go to...

As far as the jig is massless rigid body, the essential lengths are 0.28 m and 0.16 cot 55 m. The diagonal rod triangle is to give...

The touch of theta diagonal rod to the horizontal rod generate theta force whose horizontal component decides magnitude of F. Is it...

In survey of "the only horizontal bar" model, I would like to know how we should choose the shape of the pivot in this figure to...

My bad! So we have same F.

Your equation ##~L_2w=hF_x~## in #16 gives $$F_x=\frac{L_2}{h}W.$$ If you cast it in terms of the given quantities, namely ##L_1## (0.16...

My answer #16 which is same as the exam answer has sec, however post #13 answer has tan as coefficient to $$W\frac{L_2}{L_1}$$.

The blue length is important. The angle itself does not matter. Alternative orange rods are OK. The diagonal rod tansmit not only force...
