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).

Tests of Hardened Concrete in Tension

Source: Roberto Leon, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA In a previous laboratory focused on concrete in compression, we observed that concrete can withstand very large stresses under uniaxial compressive forces. However, the failures observed were not compressive failures but failures along shear planes where maximum tensile forces occur. Thus, it is important to understand the behavior of concrete in tension and particularly its maximum strength...

Tension

Tension is a force along the length of a medium, in particular, a force carried by a flexible medium, such as a rope or cable. The word "tension" comes from Latin, meaning "to stretch". Not coincidentally, the flexible cords that carry muscle forces to other parts of the body are called tendons. Any flexible connector, such as a string, rope, chain, wire, or cable, can exert pull only parallel to its length; so, a force carried by a flexible connector is a tension with a direction parallel to...
FAQs
Tension presses the flexible belt against the pulley surfaces, creating the normal force required for friction. That friction allows motion and power to pass between rotating components rather than the belt moving independently of the pulleys. In engineering analysis, tension therefore affects whether the drive can transmit motion effectively under operating conditions.
The two sides of a working belt do not carry the same tension. The higher tight-side tension and lower slack-side tension create a tension difference around the pulley, and that difference produces torque. This relationship explains why engineers consider both sides of the belt rather than treating the belt tension as a single uniform force.
Insufficient tension can allow the belt to slip on the pulleys, reducing effective motion and power transmission. Excessive tension creates greater loads on the belt and the supporting bearings. Engineers therefore seek a suitable tension level that limits slip while avoiding unnecessary mechanical loading, helping the drive operate efficiently and reducing wear.
Engineers assess the tension condition of a belt drive and adjust it to support effective motion and power transmission. The adjustment must address both major failure risks: too little tension, which can cause slip, and too much tension, which raises belt and bearing loads. This assessment supports more efficient, reliable operation and reduced wear.
Belt tension matters wherever flexible belts transfer motion or power between rotating components. The overview identifies conveyors, vehicles, industrial machinery, and power transmission systems as important examples. In each setting, suitable tension supports the intended drive function, while poor tension can contribute to slip, excess loading, reduced efficiency, or increased wear.
Properly managed tension can improve efficiency, reduce wear, and support reliable operation of a belt-driven system. It helps maintain the friction needed for transmission while avoiding the excessive belt and bearing loads associated with over-tensioning. These outcomes make tension assessment relevant to the design, maintenance, and operation of mechanical engineering equipment.
