Equilibrium of a wood stack formed by close-packed cylindrical logs [PDF]
Revista Brasileira de Ensino de FísicaThe static equilibrium of cylindrical wood pieces in a close-packed order is analyzed. By considering the coefficient of static friction μ L between two adjacent logs and the coefficient of static friction μ G between the logs and the ground, it ...

THE COEFFICIENTS OF STATIC AND KINETIC FRICTION USING ARDUINO
Jurnal Pena SainsThe friction coefficient plays an essential role in various aspects of daily life. In transportation safety, the friction coefficient between vehicle tires and the road is critical for safety. In design and construction, friction between structural components contributes to building stability.

Advanced Healthcare Materials, EarlyView.ABSTRACT Sutures are crucial for tissue approximation and wound healing. Besides their strength limits requirement, they often fail to effectively address complications like infection and pain. Inspired by natural silk's “core‐sheath” structure, our suture features a wet‐spun core of n zinc‐fortified silk fibroin fibers (RSF‐Zn2+) after drawing with ...
