NALYTICAL ML( HANKS which distinguishes the pivot from the journal bearing is this: in the former the lever arm of the frictional force varies from point to point, while in the latter it is constant and equals the radius of the shaft. Let dN be the normalreaction upon dA, an ele-ment of area at the… … TTdup. Fig. 39. The expression for the resisting torque due to the frictionIs obtained as follows: G=f*r.dF= I r • updA = fl rup . rdd • dr Jo Jo = irup I r2 dr = f Trasnp= | aixP,where P is the total load on the pivot.
