Why were handcuffs ever made with a chain between them?
I've noticed that modern handcuffs are always attached directly to each other, without any "chain" of any length in between. I guess I can understand why that make them safer and more robust....

How is motor torque related to capstan equation?
I know that capstan equation relates $T_{in}$ and $T_{out}$ as $T_{out} = T_{in}e^{u \cdot F_c}$, where $u$ is friction coefficient and $F_c$ is wrap (slip) angle. In my situation, the capstan is ...

When calculating a force, why do I get different result when I try to calculate via torque vs via sum of forces at an axis?
If I just do it by writing that the sum on y axis is 0 I get
$100+x=200$
$x=100$
If I try torque around the top:
$x*800=200*500$
$x=125$
So what am I doing wrong?

I have a quick question related to the topic of mechanics of materials.
If I were to have a beam that is fixed at both ends and has a central point force, do moments develop at the fixed supports?
e....
