Rolling Without Slipping

People have observed the rolling motion without slipping ever since the invention of the wheel. For example, one can look at the interaction between a car's tires and the surface of the road. If the driver presses the accelerator to the floor so that the tires spin without the car moving forward, there must be kinetic friction between the wheels and the road's surface. If the driver slowly presses the accelerator, causing the car to move forward, the tires roll without slipping. It is essential...

Rolling With Slipping

Rolling with slipping is a physical phenomenon that occurs when a rolling object experiences both rotational and linear motion but also experiences frictional forces that cause slipping. This phenomenon can occur in various situations, such as when a tire rolls on a wet road or a ball rolls on a rough surface. An object's rolling motion is characterized by its rotation around its axis, while linear motion refers to the object's translational motion along a surface. Frictional forces can affect...

This article outlines a versatile method to create cell-derived tissue rings by cellular self-assembly. Smooth muscle cells seeded into ring-shaped agarose wells aggregate and contract to form robust three-dimensional (3D) tissues within 7 days. Millimeter-scale tissue rings are conducive to mechanical testing and serve as building blocks for tissue assembly.

Different levels and patterns of fluid shear are known to modulate endothelial gene expression, phenotype and susceptibility to disease. We discuss the assembly and use of 'shear rings': a model that produces unidirectional, periodic shear stress patterns. Shear rings are simple to assemble, economical and can produce high cell yields.

We are developing a dynamic adaptive exposure technique using our scanning beam digital X-ray system. Rather than exposing an object uniformly, the exposure is adapted depending on the opacity of the object. Here we show an experiment on an anthropomorphic phantom that resulted in a dose saving of 30%.
FAQs
The conductive rings rotate with the shaft while the stationary brushes or contacts remain pressed against their surfaces. This sliding interface preserves electrical continuity as the shaft turns, allowing power, control signals, or data to pass between moving and fixed sections. Engineering performance depends on maintaining dependable contact while limiting contact resistance, wear, and electrical noise.
Current capacity, rotational speed, contact resistance, wear, electrical noise, and maintenance requirements all shape performance. Higher electrical loads affect current-capacity demands, while faster rotation can increase the importance of contact behavior and wear. Designers must balance these variables rather than optimize only one, because improving one characteristic can influence reliability in the overall rotating system.
Contact resistance affects how efficiently electrical power and signals cross the sliding interface. If resistance is not controlled, the connection may become less dependable and can contribute to electrical noise or performance variation. For this reason, resistance is evaluated alongside current capacity, speed, wear, and maintenance needs when engineering a slip ring for continuous operation.
The required function determines which performance concerns receive the greatest attention. Power-transfer applications emphasize suitable current capacity, while signal and data paths require dependable electrical contact and controlled electrical noise. The same rotating interface may support electricity, control signals, or data, so engineers select and balance design characteristics according to the type of transmission required.
Selection begins with the system's transmission needs and operating conditions. Engineers consider whether the assembly must carry electrical power, control signals, data, or a combination, then assess current capacity, rotational speed, contact resistance, wear, electrical noise, and maintenance requirements. Matching these characteristics to the application supports dependable operation in systems with continuous rotation.
Slip rings support rotating equipment such as motors, generators, wind turbines, robotics, radar platforms, and medical imaging equipment. In each case, they allow electrical power or information to cross between stationary and rotating sections without interrupting continuous motion. Their value is greatest where reliable transmission must coexist with repeated rotation and demanding operating requirements.
