It means, the roller support will move freely along the surface without resisting horizontal force. This type of support is provided at one end of bridge spans. The reason for providing roller support at one end is to allow contraction or expansion of bridge deck with respect to temperature differences in atmosphere.
How can the Normal Force on an upside down roller-coaster ...
There isn't "the centripetal force" like there is "the Normal force" or "the force of gravity". "Centripetal" is a direction, just like horizontal and vertical, up and down, left and right, etc. It is always true that $mathbf F_text{net}=mmathbf a$ by Newton's second law.

On top of a hill. The only forces acting on the rider are the upward normal force n exerted by the car and the downward force of gravity w, the rider's weight.These add together, as vectors, to provide the net force F net which is the centripetal force F c, directed toward the center of the circle. The normal force may also be called the rider's "apparent weight" for this is the force of …

Motion in a Vertical Circle - HyperPhysics Concepts
Motion in a Vertical Circle. The motion of a mass on a string in a vertical circle includes a number of mechanical concepts. It must satisfy the constraints of centripetal force to remain in a circle, and must satisfy the demands of conservation of energy as gravitational potential energy is converted to kinetic energy when the mass moves downward. The velocity must increase as …
Effect of travel speed and vertical load on the subsoil ...
Subsoil forces and displacements were measured at depths of 50, 100, 150, and 200 mm. Roller operating conditions included roller travel speed, the vertical load, and number of passes. Three travel speeds, 1, 3, and 5 km h-1 and three vertical loads 20, 40, and 60 kN were tested. The draft needed to move the roller was also recorded.

the vertical member 4. Now note that member 2 is also a two-force member, but it is in compression rather than tension. Therefore, we know that the forces on points D and F are equal and that they act in line with member 2, 31.0° with respect to the horizontal. The reactions to these forces, then, act at point D on the vertical support, member 4,
6.3 Centripetal Force – College Physics
Any force or combination of forces can cause a centripetal or radial acceleration. Just a few examples are the tension in the rope on a tether ball, the force of Earth's gravity on the Moon, friction between roller skates and a rink floor, a banked roadway's force on a car, and forces on the tube of a spinning centrifuge.
SOLUTION
friction force does negative work since it acts in the opposite direction to that of displacement. The normal reaction N, the vertical component of 800 N and 1000 N force and the weight of the crate do not displace, hence they do no work. Since the crate is originally at rest, . Applying Eq. 14–7, we have s = 1.35m Ans.

vertical load. As soon as a lateral load of any kind pushes on the structure it will roll away in reponse to the force. The lateral load could be a shove, a gust of wind or an earthquake. Since most structures are subjected to lateral loads it follows that a building must have other types of support in addition to roller supports. PINNED SUPPORTS
