Reference: The Tientsin Eye Ferris Wheel

The Tientsin Eye Ferris Wheel, officially named the Yongle Bridge Tientsin Eye, is the only Ferris wheel in the world built on a bridge, providing a unique vantage point for viewing the surrounding landscape. The Ferris wheel spans the Haihe River and offers stunning views of Tianjin. Understanding the dimensions and operation of the Tientsin Eye can provide insights into its engineering marvel and the experience it offers to visitors.

Basic Dimensions and Rotation

Radius

The Tientsin Eye has a radius of 55 meters. This measurement is critical for understanding the geometry and overall scale of the Ferris wheel. The radius directly influences the height of the Ferris wheel's highest point and the trajectory of its passenger cabins.

Height

The highest point of the Tientsin Eye Ferris wheel reaches a height of 120 meters above the ground. This height is achieved when the cabins are at the topmost position of the wheel, giving passengers a panoramic view of the city and the Haihe River below.

Rotation Speed

The Ferris wheel rotates counterclockwise at a constant speed, completing one full rotation every 30 minutes. This consistent rotation speed ensures a smooth and predictable experience for passengers, allowing ample time to enjoy the views and take photographs.

Photographing the Haihe River

Boarding and Ideal Photographing Height

Nan Yuan, a photography enthusiast, boards the Tientsin Eye Ferris wheel at the lowest point, which is just above the ground. To capture the best views of the Haihe River, she needs to be at a height exceeding 92.5 meters above the ground. The radius and rotation of the Ferris wheel determine when she reaches this ideal height.

Conclusion

In the 30-minute rotation cycle of the Tientsin Eye Ferris wheel, Nan Yuan can capture the most beautiful views of the Haihe River for approximately 7.76 minutes. This period allows her to take breathtaking photographs from the optimal height, making her ride a memorable experience.
