Propulsion and Thrust

Source: Alexander S Rattner; Department of Mechanical and Nuclear Engineering, The Pennsylvania State University, University Park, PA Aircraft, rockets, and ships produce propulsion by accelerating surrounding fluid or high temperature combustion products to high velocity. Because of the principle of conservation of momentum, the increased fluid velocity results in an effective thrust force on the vehicle. The thrust capabilities of propulsion systems are often measured with static thrust tests.

Source: Prashin Sharma and Ella M. Atkins, Department of Aerospace Engineering, University of Michigan, Ann Arbor, MI Multicopters are becoming popular for a variety of hobby and commercial applications. They are commonly available as quadcopter (four thrusters), hexacopter (six thrusters), and octocopter (eight thrusters) configurations. Here, we describe an experimental process to characterize the multicopter performance. A modular small hexacopter platform providing propulsion unit...

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).
FAQs
Compression acts across sedimentary layers to shorten and thicken the crust. Rock layers buckle into folds, while low-angle thrust faults accommodate displacement and stack material. Together, these structures record how convergence builds relief and reorganizes the crust through time in a convergent region.
Imbricate fault systems create stacked, overlapping structural slices during crustal shortening. Their association with foreland basins links deformation in the mountain-building zone with adjacent lowland settings. Studying both features together helps researchers trace how compression is distributed and how sediment transport responds to the evolving tectonic landscape.
Changes in relief can redirect drainage, increase erosion, and modify sediment transport across a region. Those effects connect rock deformation with surface processes, because newly organized topography influences where water flows and where eroded material is deposited. The same structural setting can also affect groundwater distribution and hydrocarbon reservoir locations.
Researchers interpret the arrangement of folded layers, thrust faults, imbricate systems, and adjacent foreland basins as a record of crustal shortening and thickening. Comparing these linked structures reveals the sequence and style of deformation, supporting reconstructions of mountain building and environmental change through geologic time in a region.
Environmental studies of these belts track how tectonic deformation changes topography, drainage, erosion, and sediment transport. This perspective connects deep crustal shortening with surface conditions, allowing researchers to examine how mountain building reshapes landscapes and redistributes sediment. It also helps place groundwater and hydrocarbon reservoirs within their structural setting.
They are useful when researchers assess earthquake and landslide hazards or evaluate subsurface resources. The architecture of folds, thrust faults, and related basins provides geological context for identifying areas where deformation affects slope stability, groundwater distribution, or hydrocarbon reservoir placement. This makes the subject relevant to environmental risk assessment and resource evaluation.
