Tensioner. A tensioner is a device that applies a force to create or maintain tension. The force may be applied parallel to, as in the case of a hydraulic bolt tensioner, or perpendicular to, as in the case of a spring-loaded bicycle chain tensioner, the tension it creates. The force may be generated by a fixed displacement, as in the case of ...

The kinetic energy of the roller coaster is: where v is the speed of the roller coaster. If we assume no friction losses, then energy is conserved. Therefore, Thus, mass cancels out, and This result is nice because it allows us to approximate the speed of the roller coaster knowing only the vertical height h that it fell (on any part of the track).
Explain in physics terms how a roller coaster works. Discuss the effects of gravity and friction in the context of their roller coaster designs. Use the principle of conservation of energy to explain the layout of roller coasters. Identify points in a roller coaster track at which a car has maximum kinetic energy and maximum potential energy.
The following is the working principle drawing of symmetrical 3 roll bending machine. Driven roller Ⅱ, Ⅲ is driven by motor and reducer, which rotates in the same direction at the same speed (or in the opposite direction). Because of the friction between the roller and the plate, the plate is driven forward and the roller is rotated.

ROLLER SUPPORTS Roller supports are free to rotate and translate along the surface upon which the roller rests. The surface can be horizontal, vertical, or sloped at any angle. The resulting reaction force is always a single force that is perpendicular to, and away from, the surface. Roller supports are commonly located at one end of long bridges.

The three high rolling mill utilizes the principle of passing the work back and forth to achieve a series of reductions. Unlike the two high reversing mill, the three high mill has three rolls that always spin in the same direction. An elevator mechanism lifts and lowers the work so that it can be passed back and forth through the rolls.
