You are correct that the only two horizontal forces acting on the block are static friction, and the force due to the tension in the rope. If the tension force is *just about* to overcome static friction, what must be true about the value of Ft as compared to Fs, and what is the...
The COH is the value which describes the ratio of the force of friction between two bodies and the force pressing them together. They range from near zero to greater than one, depending on the types of materials used.For example, ice on steel has a low coefficient of friction, while rubbe...
The equation is simply written fx = μxF, where fx defines the form and measure of friction, while F is the perpendicular or "normal" force exerted by both surfaces, one upon the other. All coefficients of friction are dimensionless, scalar quantities; individual contributing factors resist ...

Friction is the resistance to motion of one object moving relative to another. According to theInternational Journal of Parallel, Emergent and Distributed Systems, it is not treated as a fundamental force, likegravityorelectromagnetism. Instead, scientists believe it is the result of the electromagneti...
Forces can also be static, like the force of friction preventing movement. 7 How is strength measured in materials? It can be measured in terms like tensile strength, compressive strength, etc., depending on the force applied. 7 Can force be a measure of strength? Not directly. Force is ...
