Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Tribological tests are adopted to estimate the kinetic friction coefficient (COF) of the material of interest according to the American Society for Testing and Materials (ASTM) standard. Typically, ...

To calculate the friction coefficient, first identify which forces are acting on the object. These include the normal force (N), gravitational force (F_g), applied force (F_a), and either static or ...

Kinetic friction, often referred to as sliding or dynamic friction, is a force that resists the relative motion between two surfaces in contact. Understanding how to calculate kinetic friction is ...

Kinetic Friction Kinetic friction, also known as sliding friction, is the force that opposes the motion of objects in contact when they are already in motion. It acts in the direction opposite to the ...

This allows us to perform dynamic simulations of friction in real materials with DFT accuracy and to isolate the effect of the in-plane stiffness on the superlubricity from the corrugation of the ISES ...

During the investigation, it is observed that (i) friction coefficient is sensitive to vehicle speed and braking pressure (ii) fade test records a maximum brake disc temperature of 403°C (iii) ...
