Does without slipping mean no friction? For many dynamics problems, rolling without slipping means there is a friction force acting on the wheel at the contact point P. This friction force prevents slipping. In this instance the friction is known as static friction since there is no relative sliding between the wheel and surface at […]

What does tightening a string do?
What does tightening a string do? Tension refers to how tightly the string is stretched. Tightening the string gives it a higher frequency while loosening it lowers the frequency. When string players tighten or loosen their strings, they are altering the pitches to make them in tune. The density of a string will also affect […]

How do you calculate area with pressure and force?
How do you calculate area with pressure and force? Pressure and force are related, and so you can calculate one if you know the other by using the physics equation, P = F/A. Because pressure is force divided by area, its meter-kilogram-second (MKS) units are newtons per square meter, or N/m2. How is area related […]
What is the 2nd harmonic also referred to?
What is the 2nd harmonic also referred to? Second Harmonic Such positions are referred to as nodal positions or nodes. The lowest possible frequency at which a string could vibrate to form a standing wave pattern is known as the fundamental frequency or the first harmonic. Which generators have the lowest THD rating? The A-iPower […]
