Static Friction

open access: yes, 2011
Static friction is the force between two objects that are not moving relative to one another. This Demonstration shows what applied force is needed to overcome this static friction (and thus begin moving).

THE COEFFICIENTS OF STATIC AND KINETIC FRICTION USING ARDUINO

open access: yesJurnal Pena Sains
The 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.

Rational Tuning of Hygroscopic Oscillation of Stacked Nanoflake Assemblies for Continuous Ambient Energy Harvesting

open access: yesAdvanced Materials, EarlyView.
Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...

Can Elastomers Combine Stiffness, Toughness and Fatigue Resistance?

open access: yesAdvanced Materials, EarlyView.
This review studies how the molecular and macroscopic architecture of elastomers influence their mechanical properties including: stiffness, stretchability, toughness, fatigue resistance, and damping behavior. By linking the structure to performance, it proposes design principles for advanced elastomeric systems that combine mechanical properties ...
