r this clement ofsurface, and d¥ be the corresponding frictional force; then we have dF = n dN = iip • I -a do, where p is the normal reaction per unit area or the pressure,a is the radius of the shaft, and / the length of the bearing. 52 ANALYTICAL MECHANICS Therefore the total frictional force… … Fig. 38. of dependence of p upon 0. But whatever the relationbetween p and 0 it is obvious that the sum, over all the sur-faces of contact, of the vertical component of the normalreaction must equal the load which rests upon the bear-ings. If P denotes this load, then ;; must satisfy the condi-tion…
