DEFORMATION AND STIFFNESS OF SPUR GEAR TEETH AND THEIR INFLUENCE ON GEAR NOISE
Scientific Journal of Silesian University of Technology. Series Transport, 2015 Gear teeth are deformed due to the load. The deformation of gear teeth is causing some negative as well as positive effects. A tooth has a complex shape and due to the complex shape of the teeth, a theoretical determination of the deformation is difficult.

Concussed: Unintended Consequences of the Guardian Cap Mandate in the NFL
Southern Economic Journal, EarlyView.ABSTRACT Guardian Caps are padded shells worn over American football helmets to cushion impacts and reduce concussion risks. In 2022, the NFL mandated their use for specific position groups during preseason practices, later expanding this requirement. While the league praised the Caps for enhancing player safety, skeptics argue they may promote riskier
