The scalability and resolution of conventional optical manipulation techniques are limited by diffraction. We circumvent the diffraction limit and describe a method of optically transporting nanoparticles across a chip using a gold surface patterned with a path of closely spaced C-shaped plasmonic resonators.

Frictional Forces on Flat Belts

Flat belts are commonly used in various industrial applications for transmitting power from one pulley to another. When a flat belt is wrapped around a set of pulleys, it experiences different tensions at the driving pulley ends due to the friction between the belt and pulley surface. When the pulley moves in a counterclockwise direction, the tension T2 on the opposite side of the pulley where the belt is moving away from is higher than the tension T1 on the side where the belt is moving...

We describe a protocol for investigating human locomotor adaptation using the split-belt treadmill, which has two belts that can drive each leg at a different speed. We specifically focus on a paradigm designed to test the generalization of adapted locomotor patterns to different walking contexts (e.g., gait speeds, walking environments).

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Visual mental imagery refers to the ability to conjure images in one’s mind’s eye. This allows people to process visual material above and beyond the constraints of a current point-of-view; for example, a person could imagine, using their mind’s eye, how something might look in a different color, or what it would look like if it were made from a different material or rotated and seen from a different perspective. Mental imagery...

Flat Belts: Problem Solving

Flat belts are crucial in many industrial applications as they help transmit power from one pulley to another. The concept of forces and moments is used to determine the maximum moment on a pulley. For instance, consider a flat belt that wraps around two pulleys, A and B, with radii of 30 cm and 10 cm, respectively. The angle between the belt and the horizontal is 20 degrees at the pulleys. As pulley B rotates clockwise and drives pulley A, tension T2 is caused at one end of the belt, while...
FAQs
Belt speed is set by the driving pulley’s angular velocity and radius. Increasing either quantity increases the speed at which the belt travels, provided the belt remains engaged with the pulley. This relationship lets investigators connect rotational motion at the pulley to translational motion along the belt and examine how changes in rotation affect the whole system.
Torque transmission depends on unequal tension on the two sides of the belt. The driving pulley pulls more strongly through the higher-tension side, while the tension difference produces the turning effect transferred to another pulley. Examining this imbalance helps distinguish simple belt motion from the mechanism by which a rotating system delivers mechanical energy.
Friction at the contact between pulley and belt is essential because it makes the belt follow the pulley’s motion. Without that interaction, rotation would not effectively produce belt movement or transmit torque. In a physics investigation, changing or observing the frictional interaction provides a way to study how force, motion, and energy transfer are connected.
A basic investigation can begin by observing a belt loop connecting rotating pulleys, then relating the driving pulley’s angular velocity and radius to belt speed. Researchers can compare the tension on the belt’s two sides and observe the resulting motion or torque transfer. This setup supports focused study of friction, circular motion, and rotational dynamics without treating them as isolated ideas.
Rotating belt systems are useful when motion must be transferred between rotating components. Conveyors apply the arrangement to move material, while engines and power-transmission systems use it to pass mechanical energy between pulleys or wheels. These examples connect classroom analysis of tension and torque with practical systems in which rotational motion produces useful movement.
In physics, studying this system can reveal how angular velocity, pulley radius, friction, and tension jointly influence motion and energy transfer. Measurements or observations can be interpreted through rotational dynamics and mechanical advantage, showing whether a change in the rotating components alters belt speed, torque transmission, or the useful mechanical effect produced by the system.
