A Preliminary Analysis of Relationships Between a 1RM Hexagonal Bar Load and Peak Power with the Tactical Task of a Body Drag

Journal of Human Kinetics, 2019
A critical job task for law enforcement officers that should be influenced by strength is the body drag. This study analyzed relationships between absolute and relative strength measured by a one-repetition maximum hexagonal bar deadlift (1RM HBD), with ...

Integrated Design of a Morphing Winglet for Active Load Control and Alleviation of Turboprop Regional Aircraft

Applied Sciences, 2021
Aircraft winglets are well-established devices that improve aircraft fuel efficiency by enabling a higher lift over drag ratios and lower induced drag. Retrofitting winglets to existing aircraft also increases aircraft payload/range by the same order of ...

Development of High Efficiency Dog Clutch with One-Way Mechanism for Stepped Automatic Transmissions

International Journal of Automotive Engineering, 2019
In order to reduce drag losses and a clutch actuator load, the new dog clutch system for stepped automatic transmission is developed. Transmitting torque is converted to the engaging force because rotating shaft and dog clutch are connected with the ...

Stresses and Drag in Turbulent Bed Load From Refractive Index‐Matched Experiments

Geophysical Research Letters, 2018
We report steady open‐channel flow experiments that resolve the internal dynamics of turbulent bed load layers at subgrain diameter resolution. Optical access is gained by using materials of matched refractive index, and a laser light sheet is scanned ...

Nanofriction mechanisms derived from the dependence of friction on load and sliding velocity from air to UHV on hydrophilic silicon [PDF]

, 2005
This paper examines friction as a function of the sliding velocity and applied normal load from air to UHV in a scanning force microscope (SFM) experiment in which a sharp silicon tip slides against a flat Si(100) sample.

Numerical and analytical modeling for predicting drag load induced on pile in collapsible soil because of inundation

, 2017
Negative skin friction that develops on the pile surface when the soil (adjacent to the pile shaft) settles but the pile is in static condition, causes an additional load (known as drag load) induced on pile.

An experimental study on drag forces on obstacles in granular flow [PDF]

EPJ Web of Conferences
The present work examines the interaction between granular flow and cylindrical obstacles. The experiments are conducted on an inclined chute where single or two cylinders are positioned at varying distances, with load cells to calculate drag forces and ...
