The red line in the graph from Fig. 1.21 is the trend line. For friction with a normal force of 120 N, the linear fitting gives a good approximation. For FN = 120 N the trend line is described by the equation μ = −0,0,023,468 × vs + 0,87,555 with R-squared = 0.965. ...
In a graph of kinetic friction vs. normal force, the slope is found to be 3.33. What information is provided by the slope? Determine the friction force between the block and the surface. How to solve inclined plane p...
Typical traces of shear force vs. time for the sliding mica surfaces across: d PoPF, e XGH, and f 2XGH/PoPF. The uppermost trace in each graph shows the back-and-forth lateral motion applied to the upper surface, whereas the other traces show the forces transmitted to the lower surface...

Figure 1 —COF vs Normal Force. Static friction between strings is determined by the surface characteristics of the main and cross that are moving against each other as well as the force pushing them together. Strings are pushed together by weaving and then pulling to tension. But the main co...
Friction (Static and Kinetic) CHS Physics Motion in Two and Three Dimensions. Position The position of an object in two or three dimensions is given by a position vector. The vector.
that the weight and the material, but not the base area, influence the frictional force, the decrease in force when the block begins to move, due to the lower dynamic friction compared to the static friction (a ‘shark tooth’, see Fig. 2a), and ripples in the graph (Fig. 2b), due...
where FS is the Stribeck friction force, v is the sliding speed, μ is the coefficient of friction and N is the normal load in the contact. FS0 is the maximum static friction force, vs is a sliding speed coefficient, kv is a viscous coefficient and i is an exponent. The Stribeck fric...
The graph of coefficient of friction versus sliding cycles for different loads is obtained [68]. Pin on disc tester is another tribometer device that can measure the friction force by the load cell and the coefficient of friction from the load. The friction is created by a pin sliding on ...
