Study Notes
Roller Coaster History and Design
- Roller coasters originated in Russia, with early models featuring wooden and ice slides for winter festivals.
- These early coasters were tall, often reaching the height of an eight-story building.
- Initially, sleds were carved from ice blocks, lacking brakes, and relied on sand at the bottom for slowing down.
Evolution of Roller Coaster Design
- Later models in France incorporated wheeled cars locked to tracks, marking a significant advancement in safety.
- Early roller coasters were associated with many accidents.
- A prime example is the Switchback Railway at Coney Island, opened in 1884, featuring a small train ride down a 600-foot slope. This early coaster had a top speed of only six miles per hour.
Modern Roller Coaster Features and Developments
- Modern advancements include new wheels preventing track departures and safety chains to prevent backward movement.
- Track inclines (banking) on turns improve speed and smoothness.
- Today's roller coasters are diverse in style and speed, with examples like the Top Thrill Dragster in Ohio achieving speeds of 120 miles per hour.
Roller Coaster Design Principles
- Roller coaster design prioritizes safety alongside speed, twists, loops, and thrilling drops.
- The planning and modeling process involves careful computer simulations.
- Roller coaster construction is divided into parts, assembled, and comprehensively tested before public opening.
- The design is heavily reliant on understanding gravity's influence. Potential energy at the hill's summit transforms into kinetic energy as the cars accelerate.
- Forces like friction are vital considerations in the design process.
Roller Coaster Construction Time
- The design and development process for a new coaster takes approximately a year.
