Bearings and other parts requiring exceptionally low friction and wear can be fabricated from an acetal polymer with an addition of polytetrafluoroethylene (PTFE) fibers. The densities of acetal and PTFE are 1.42 Mg/m³ and 2.15 Mg/m, respectively. If the density of the polymer with additive is 1.54 Mg/m³, calculate the weight percent of the PTFE addition.
