Find the contact parameters ( R', b, pmax, paverage, Pmaxand z) for two parallel steel rollers. The normal force is W = 5[N], radii of the rollers are RA= 10*10-3[m] and RB= 15*10-3[m], Young's modulus for both rollers is E = 2.1*1011[Pa] and the Poisson's ratio is v= 0.3. The length of both rollers is 2l = 10*10-3[m].
