The next type of roller coaster is steel. The steel roller coaster changed the world in the early 1950’s. Its supported by long steel tubes and
slightly larger lightweight steel tubes. Typically the wheels are made from polyurethane or nylon. Also The wheels are on top, bottom, and sides. This keeps the roller coaster on the track when doing loops and turns. The steel roller coaster can also have the on top and the train upside down. The steel coaster also ensures a smoother ride than the wooden cause it doesn’t wobble as much.
The other type of roller coaster is suspended. A suspended roller coaster is a type of steel coaster in which the car is hanging by a hinge assembly. This also allows the car and riders to swing side to side as the train races along the track. Also this allows to have the experience of moving side-to-side. The earliest suspended roller coaster was built in the early 1900’s Bisby's Spiral Airship in Long Beach California. The last type of roller coaster is inverted roller coaster. The inverted roller coaster is attached to the tracks so designers having more ideas to have. The coaster is supported by tubular steel track prefabricated in large, curved segments. This design allows smooth turns, loops, and other things. On a wooden roller coaster the coaster rattles because it is joined by bolts and on the inverted the tubular steel is welded so it allows a smooth ride. The coaster runs under the track but swings via a pivoting bar attached to the wheel carriage. The coasters design allows the passengers feet to dangle causing a more triller experience.
