Notice that a roller is used at the end of the follower. In addition, a spring is used to maintain the contact of the cam and the roller. If you try to calculate the degrees of freedom (DOF) of the mechanism, you must imagine that the roller is welded onto the follower because turning the roller does not influence the motion of the follower.

roller coaster, elevated railway with steep inclines and descents that carries a train of passengers through sharp curves and sudden changes of speed and direction for a brief thrill ride. Found mostly in amusement parks as a continuous loop, it is a popular leisure activity.. Overview. On a traditional roller coaster, gravity powers much of the trip. The potential energy for the …
Cars in roller coasters always move the fastest at the bottoms of hills. This is related to the first concept in that at the bottom of hills all of the potential energy has been converted to kinetic energy, which means more speed. Likewise, cars always move the slowest at their highest point, which is the top of the first hill.

The magnitude of the force acting on the roller coaster car (or passenger) can be calculated using the formula F GRAV =m.g, where the acceleration due to gravity is represented by g (where g=9.8 m/s 2).The magnitude of the normal force depends on three factors—the speed of the car, the radius of the loop, and the mass of the rider. As depicted in the free body …

It is best that the initial roller coaster slope not be steeper than ±2.5, otherwise the marble may slide instead of roll. This guideline is an outcome from testing different initial slopes. It is recommended that inches be used for the measurements and calculations because all construction and auxiliary materials are measured in inches.

The top-mounted roller controls the movement of two bottom-mounted rollers. The roller gears are 23 teeth mesh, which means that the three rollers depend on each other. The two other rollers move at the same speed as the top roller shaft, but in the same direction. The transmission is carried through the gear motor to two more rollers.

Although, flat followers are used by engineers to operate the valves of an engine whereas roller followers are used by engineers in oil and stationary engines. This type of preference occurred due to more availability of space of roller followers. A Simple Cam, Follower Mechanism:
On a roller coaster, energy changes from potential to kinetic energy and back again many times over the course of a ride. Kinetic energy is energy that an object has as a result of its motion. Traditionally, the coaster cars are pulled up the first hill by a chain; as the cars climb, they gain potential energy .
Rollers are the construction equipment used for the compaction of soil, gravel, sand, crushed stone layers, etc. Roller working principle is based on vibration, impact loading, kneading and by applying direct pressure on the respective layer. The four most commonly used rollers are; Vibratory Roller Tamping roller/ sheep foot rolle
Roller followers are extensively used in stationary gas and oil engines. They are also used in aircraft engines due to their limited wear at high cam velocity. While working on the concave surface of a cam the radius of the surface must be at least equal to the radius of the roller. Advantages of Roller Follower over Knife Edge Follower
