Question

The durability of devices that reduce this quantity is rated by the L10 life. Reduction in this quantity due to a thin viscous fluid film with no pressure gradient in the z-direction is described by the Reynolds equation. (0[2])A device (0[1])that effectively reduces this quantity (0[2])transmits (0[1])a load to a series (20[1])of spheres rotating between static (20[1])and moving races. (20[2]0[1])Molybdenum disulfide (20[1])and (*) graphite (10[2])are used (10[1])as (10[1]0[1])dry powders (10[2]0[1])to reduce (10[2])this quantity (10[2])instead (10[1])of fluorinated (10[1])polymers (10[1])like Teflon. (10[2])Synovial fluid reduces this quantity (10[2]0[1])in the body. (10[1])Mechanical or fluid bearings reduce the rolling or sliding forms (10[1])of (10[1])this quantity to prevent (10[1])energy being lost as heat (10[1])when two solids rub against each other. For 10 points, lubricants reduce what (10[1])“coefficient?” (10[1])■END■ (10[6])
