Mathematics & geometry
Rolling Circle Straight Line Exhibit
A hand-operated rolling-circle model turns circular motion into the apparent straight-line travel of a marked figure.
REFERENCE VIEWS · IMAGE SEQUENCE
Inspect the reference.
A fifteen-second sequence of five catalogue design images. Review the overall arrangement and component details; the sequence does not demonstrate physical operation or simulated 3D movement.
This film sequences existing reference images. It is not continuous operating footage or a moving 3D simulation; final function and configuration follow the agreed project.
THE ACTIVITY & MECHANISM
Make a rolling circle trace a straight line.
Turn the crank and follow the marked figure on the inner circle. Although the circle rolls around inside a larger one, the figure moves back and forth along a straight line. This happens when the fixed circle’s radius is twice the rolling circle’s radius, an arrangement known as a Tusi couple.
- 01
Turn the crank
Turn the crank to move the inner circle.

BEFORE AN ENQUIRY
Questions & support.
24 months of complimentary spare-parts support, remote technical guidance and long-term after-sales support. Exhibit Engineers pays the shipping cost of complimentary spare parts during the 24-month support period.
Explore the supportDelivery, installation & after-sales terms
- Payment
- A 50% deposit is payable after the contract is signed. The remaining balance is paid after acceptance and before dispatch, so full payment is received before dispatch. Payment methods are agreed in the contract.
- Packaging & transport
- Metal shipping cases or multilayer wood-panel shipping cases. Transport arrangements and costs are agreed to suit the project.
- Materials & painted finish
- Common material options include Q235 steel, stainless steel, aluminium alloy, PVC, acrylic, engineering plastics. The combination is selected for each configuration. Marine anti-corrosion paint with a piano-gloss automotive paint finish. Applied to painted parts.
- Typical power · powered versions
- Standard products: 100–500 W; oversized installations: 1,000–5,000 W. Typical ranges for powered versions. Confirm the selected model and final connected load.
- Product maintenance
- Inspect removable pieces, moving parts, fasteners and the visitor controls before use. Follow the supplied operating sequence and scheduled maintenance every 30 days.
- Installation & training
- Complimentary training is available on site or remotely, according to project needs. If installation or on-site after-sales service is not included in the product price, the customer pays the actual travel expenses incurred, unless the contract provides otherwise.
- Factory acceptance & handover
- Mid-production and pre-dispatch checks are provided. Factory acceptance can take place in person at the factory or through acceptance videos. Installation and operating videos, written installation and operating instructions, drawings and a spare-parts list are provided.
- Complimentary parts
- 24 months of complimentary spare-parts support, starting when the exhibit is handed over for use. Covers faults not caused by the user. User-caused or deliberate damage is excluded. Exhibit Engineers pays the shipping cost of complimentary spare parts during the 24-month support period.
- Warranty & repair labour
- The whole-exhibit warranty period and repair labour scope and charges are agreed in the contract.
Can we discuss a prototype or sample for a custom version?
Yes. Prototype testing and sample fabrication are available for custom projects. Discuss which functions or features you need to review for your version. The scope, cost and schedule are agreed for the project.
How prototype testing & samples workWhat can we discuss for our setting?
Share the learning theme, visitor group, room plan and preferred interaction. Confirm the appearance, dimensions, controls and interpretation for the version you need.
What should we confirm before ordering?
Review the final configuration, operating instructions, power and installation needs, maintenance access and supply responsibilities with the project team.
