A beam attached rigidly to a support has no degrees of freedom, i.e DOF=0
The next time you go to your local Shopping Center have a look at the wheels under the shopping cart. Those are caster wheels. A caster wheel is a wheel attached to the bottom of objects (notably bed frames, office chairs, and skateboards), and for carts and dollies. A caster wheel usually incorporates its own single-wheel axle. Some caster wheels can swivel, up to 360 degrees, to make turns and lateral motion possible.
Yes, they do, With the wheels under them is what makes them move. Depending on the type of robot your are distrubuting or making.
The pulley attached to the motor usually has a large wheel on bottom, two medium wheels in centre of the stack and a small one on top. The front, or spindle pulley, is fitted with the large wheel on top. The drive belt can go from top at back, to top at front -thus driving the spindle slowly. If you changed the belt to the big motor pulley and a small spindle pulley the spindle would rotate faster.
Wherever there is stress there is strain. In the example you noted, if heated bar expands freely without one end constained it changes its strain without stress; that strain is called eigenstrain. If the same bar is held rigidly then the eigenstrain resisted and you get stress and strain. So stress cannot exist without strain; but strain can exist without stress if it is eigenstrain.
